Perimeter trap cropping occurs when an attractant plant is grown around the perimeter of a cash crop, surrounding it completely. such as Superior two weeks before the rest of the crop. Perimeter trap cropping functions by intercepting pest migration, regardless of the direction of attack. best on pests that are abundant and destructive just about every year, Less spraying usually translates into lower costs. and the incomplete borders did not hold up against the beetles. Plant the trap crop (i.e. Fortunately, If planted in sufficient density trap crops can provide a physical barrier to mobile insects. This project used that concept by using an established planting of fall red raspberries as the trap crop for the SWD, planted around a day-neutral strawberry plant- ing. Results: What does PTC mean? Perimeter Trap Cropping - Trap crops that are planted around the border of the main crop. Rutgers is an equal access/equal opportunity institution. Researchers in Connecticut attempted to stop pepper maggots from infesting bell peppers by trying border sprays, a perimeter trap crop of hot cherry peppers and a combination of the two methods. Beetle populations on the unsprayed main crop in the center were reduced by up to 95%. 1). Materials tested include Entrust, Cidetrak D, Pyganic 5.0, Neemix 4.5, and Surround. Trap cropping layout Strip interplant trap . 3). Spraying the perimeter trap crop Less spraying usually translates into lower costs. If youd like to try it, here are some tips for success. encouraged to direct suggestions, comments, or complaints concerning any accessibility issues Two rows of a trap crop ('New England Blue Hubbard' in one field and 'Bird House Gourd' in the other) were seeded at the same spacing around each pumpkin field. In infected plants, vascular tissues clog with bacteria, and the plant wilts, withers, and dies. Boller, E.; Hani, F.; Poehling. in the borders of protected fields than on the main crop. When a more attractive plant is established around the field perimeter, insects moving in from wooded edges should concentrate in the perimeter trap crop and not feed on the main crop in the center. Cabbage is another crop that may be protected by PTC. Perimeter Trap Cropping (PTC) involves planting the attractive plant species so that it completely encircles the main crop, like fortress walls. Suggest. Ask for assistance from your local agriculturist. Six commercial growers employed this technique insect pests, called Perimeter Trap Cropping, or PTC. Additionally, sprays can be focused on the trap crop, reducing sprays on the cash crop. There are several articles with more details about PTC located on Cookies are OK, but I really like ice cream. Jim Jasinski & Celeste Welty . 1 vote. Increasing the species diversity in a monocrop system should help balance the ecosystem and prevent pest population explosions. For example, limited pesticide applications, targeted at the perimeter rows only, leaves most of the crop unsprayed and preserves pest natural enemies that can help prevent future crop damage. This pests is worse on some farms or fields Always consider planting tolerant varieties. The required trap crop planting size depends upon the intensity and direction of the pest attack expected, as well as the mobility of the target insect(s). PTC abbreviation stands for Perimeter Trap Cropping. 2021-70006-35582 and grant no. Our strain has been improved for uniformity on our seed farm. unsprayed main crop in the center of the plots were reduced by up to 93% Blue hubbard squash has been used in many of the PTC studies so far. larvae was measured in the main crop of the plots with a perimeter of collards Dont Adults lay eggs on the trap crop. Trial 1 - Perimeter trap cropping Perimeter trap cropping (PTC) involves planting one or more rows of a cucurbit crop that is highly attractive to cucumber beetles around the border of a main cucurbit cash crop that is less attractive to the beetles. Transplant the collards at the same time as the main crop and provide both with similar fertilizer, irrigation and cultivation programs. This trial also established 'New England Blue Hubbard' squash as an effective perimeter trap crop for 'Waltham' butternut squash. Typically, winter squash are seeded in June and July. Perimeter trap cropping is useful when it is necessary to protect the crop from an attack that may come from several or unknown directions. Over 94% of the cucumber beetles in the experiment were on plants in the perimeter. On smaller plots, the trap crap may be too close to the main crop, enabling pest movement and damage to the main crop. A trap crop barrier on all sides is useful when it is necessary to protect the crop from a pest attack that may come from several or unknown directions. Low numbers of live beetles were found on 'Bird House Gourd.' Extension specialists are working to understand By continuing without changing your cookie settings, you agree to this collection. Additionally, plow deeply and cultivate after harvest to reduce overwintering populations. Perimeter trap cropping and crop rotation should be used together to prevent some cucumber beetles from overwintering within the field, and to help prevent an increase in the pest population over time. crop, like a fortress wall. Blue Hubbard works equally well around cucumbers or melons. Cucumber beetles overwinter in woods' edges around fields and enter fields from these edges. In this study three rows of perimeter trap crop were seeded with rows 6' apart. Use in other geographical areas may be inappropriate. well-timed full-field sprays. Any opinions, findings, conclusions, or recommendations expressed in this publication are those of the author(s) and do not necessarily reflect the view of the U.S. Department of Agriculture. In a third field, 'New England Pie' pumpkin was seeded in 14 rows 150' long and at the same spacing. Remember that collard seedlings develop a little slower than traditional cole crops. Savings in pesticide costs and improvement in crop quality. attractive to cucumber beetles more attractive than standard pumpkins. Perimeter trap cropping involves planting the attractive plant species so that it completely encircles the main crop like fortress walls. Sequential Trap Cropping - Traps crops that are planted either later or earlier than the main crop to increase the attractiveness to insect pests during certain times of the season. Perimeter trap cropping is useful when it is necessary to protect the crop from an attack that may come from several or unknown directions. For the past Make a farm plan. by hand. This study observed perimeter trap cropping on a relatively large plot of butternut squash 8 acres. Dec 2021; Vanitha Khandibagur. Perimeter Trap Cropping often results in improved crop quality and dramatic pesticide savings. The University of Connecticut, Cooperative Extension System, College of Agriculture and Natural Resources is an equal opportunity program provider and employer. According to Cornell research, the materials available for organic production fail to provide adequate control of the striped cucumber beetle. planted traps crops to protect a main cash crop from a pest. Trap crops that require a small amount of space relative to the main crop are more economical, as well. No matter what directions they come from, insects . his control in the main field. The grower sprayed the Any opinions, findings, conclusions, or recommendations expressed in this publication are those of the author(s) and do not necessarily reflect the view of the U.S. Department of Agriculture. The pest control benefits of planting in a logical spatial pattern seem obvious. A trap crop barrier on all sides is useful when it is necessary to protect the crop from a pest attack that may come from several or unknown directions. Make sure the trap crop barrier remains lush all through the season to attract the pest and the barrier extends all the way around the crop you wish to protect. Slowly pull them apart. At one point and Ruth Hazzard of University of Massachusetts Extension have studied The strong perimeter-driven behavior of the brown marmorated stink bug (H. halys) and the brown stink bug (Euschistus servus Say (Hemiptera: Pentatomidae)) could potentially be increased by raising a highly attractive trap crop border in a perimeter surrounding the cash crop [7,15,16,17]. Control Measures: Measures were taken to control the pest when 10% of the plants observed had live beetles. In several Copyright 2022 Rutgers, The State University of New Jersey. Bacterial wilt is a major disease in New Jersey. One grower in 2003 planted Prizewinner as a perimeter around a field with Researchers in Connecticut have stopped pepper maggots from beetles emerge in the field edges and walk or fly into potato fields, an Observations: Beginning May 25 and continuing until the vines of the butternut began to run, we scouted twice a week, each time evaluating 100 random plants of each crop. Control efforts can then be focused on trap crops, and potential costs can be minimized.

The required trap crop planting size depends on the number of pests and the intensity and direction of the attack expected. crosswise. or just at a different stage of growth than the cash crop. Insects show preferences for certain species or varieties of plants due to morphology, relative concentration of feeding stimulants, or other factors (Cavanagh and Hazzard 2006). Collards around cabbage(Fig. Bell peppers surrounded by the trap crop produced at least 98% pest-free fruit at harvest compared with all-bell plots which had 15% of the fruit infested. It works best for insects of intermediate mobility rather than those, like aphids, passively dispersed by air currents or those strong fliers that descend on a crop from high elevations. The perimeter orientation of the trap crop and defenses improves efficacy because the barrier intercepts the pest migration regardless of the direction of attack, rather than trying to get the pest to move to where you want it to go. in six commercial fields of butternut ranging in size from two to six acres. Check the Organic Production Guide from New York State IPM and Cornell University for information on pesticides labeled for use in organic cucurbit production and always be sure to double check with OMRI and your certifier before using. This works best with insects that have an intermediate flying . 2). The University of Connecticut, Cooperative Extension System, College of Agriculture and Natural Resources is an equal opportunity program provider and employer. of beetles in the border than in the main crop. Cut the wilted stem close to the crown and rejoin the cut surfaces. Early emergence can be achieved by green sprouting It is best to make multiple sowings, several days apart, to provide an ample and continuous supply of attractive, young mustard plants that protect the main crop adequately. This research is supported by grants from the USDA NE-IPM & NE-SARE Programs and the New England Vegetable & Berry Growers Association. Perimeter trap cropping is presented as one example of an ecologically based solution. For high-value crops, floating row covers can be used to exclude cucumber beetles. of high beetle pressure and poor trap crop emergence. Beetle populations on the Pepper Pests are intercepted along the border, PTC can also be implemented using a different variety of the main rate) yield was not significantly different than uniformly treated pumpkin crop . The use of perimeter trap cropping (PTC hereafter), the subject of this grant, has been and continues to be adopted by growers in the area. In this study three rows of perimeter trap crop were seeded with rows 6' apart. heavily concentrated on the border plants. It works best on pests that are found near the borderline of the farm. A perimeter trap crop barrier of hot cherry peppers, border-row insecticide applications, and a combination of the two management strategies were evaluated to see if they could protect a centrally located main crop of bell peppers from oviposition and infestation by the pepper maggot, Zonosemata electa (Say). This strategy reduced insecticide use on the main crop by up to 94 percent, nearly eliminating sprays on the main cash crop. Six commercial cucurbit growers successfully employed the technique in 2002. UConn Cooperative Extension, Vernon, CT. April 2003, Reviewed 2012.

Cherry peppers around bells(Fig. One popular perimeter trap crop is the use of hot cherry peppers planted around bell peppers. Trap crops are more economical to use if the system is easily planted and maintained, and the crops have some other beneficial use (e.g., support beneficial insects or are marketable). Blue Hubbard around yellow summer squash(Fig. Spraying the perimeter trap crop reduced squash vine borer infestation on the unsprayed summer squash within by 88%. Kaolin is a protectant and must be applied beforebeetles move to the main crop. See: Attractiveness to Cucumber Beetles. This experiment was conducted to determine if the addition of internal trap crops to a perimeter trap crop system would be an improved organic technique for control of cucumber beetle in organic winter squash. Also, in this study, squash were seeded in May. PTC means Perimeter Trap Cropping. Put the plant the pest likes the best on the outside, and it may not need to travel any farther. A trap crop barrier on all sides is useful when it is necessary to protect the crop from a pest attack that may come from several or unknown directions.

By avoiding cover sprays in the main crop, natural enemies Source publication. There are 2 half-size cloth sheets and a full-size sheet weighted . Squash bugs: During all scouting dates, squash bug numbers were highest in the 'New England Blue Hubbard.' Perimeter trap cropping can be used for flea beetles by simply replacing the collard barrier with Chinese Southern Giant mustard. growers tended to plant a single row of a trap crop next to a cash crop. Commercial farmers using PTC harvested 99.99% For some pests, Perimeter Trap Cropping may work in very small (garden-size) plots but, for others, larger plantings may be required. There are two forms of trap cropping; perimeter trap cropping (PTC), also known as border trap cropping, and row intercropping. Trap Crop: 'New England Blue Hubbard' squash.

Drive a planter across the ends of the rows, in order to plant For the past few years, Jude Boucher of the University of Connecticut Cooperative Extension and Ruth Hazzard of University of Massachusetts Extension have studied PTC by conducting trials on research farms and in grower's fields. Also see: Options for Managing Bacterial Wilt Affecting Cucurbit Crops from Cornell University and Cucumber Beetles: Organic and Biorational Integrated Pest Management from ATTRA. What are some other good sources of information? Trap cropping provides another alternative to chemical pest control. Trap cropping is the planting of a trap crop to protect the main crop from a pest, by having the trap crop appear more attractive to the pest than the main crop. The DBM population on the collard plants around the cabbage exceeded threshold in 89% of the fields, but a naturally occurring parasitic wasp,Diadegma insulare, helped control the population and keep it from spilling over into the cabbage. Despite the fact that See: Attractiveness to Cucumber Beetles. See: Managing Striped Cucumber Beetle in Vine Crops from University of Massachusetts. or your tomato, using Vittoria as a PTC may help, although results are Basavaraj Biradar. If using row covers, remove covers at flowering so as not to reduce pollination. Typically, winter squash are seeded in June and July. In recent years, Perimeter Trap Cropping has dramatically increased the efficacy of trap cropping on a variety of crops. pest infestation is high. Prizewinner, a giant pumpkin variety, is highly Does this study apply to my farm? All but one said the system was simpler to use and saved them Any reference to commercial products, trade or brand names is for information only, and no endorsement or approval is intended. This technique may also improve the efficacy of full-field sprays for tough pests by restricting most of the damage to the perimeter area. (Fewer beetles were found on pumpkins in fields with trap crops.) In experiments, bell peppers surrounded by the trap crop produced at least Researchers in Florida were able to keep the DBM from reaching action thresholds in nine commercial cabbage fields by surrounded them with two rows of collards. attractive to striped cucumber beetles, has vigorous seedlings, and is potato beetle (CPB) and eggplant flea beetle (FB) prefer the elongated Less spraying usually translates into fewer safety concerns. How do I know if my squash has bacterial wilt?

If you have to cultivate out some plants in the row middles, Unfortunately, selective insecticides are not yet available to aid in flea beetle control. rather than for pests that only appear once in a while in your location. Pest: Striped cucumber beetle (Acalymma vittatum, Fabricius). Perimeter Trap Cropping often eliminates the use of broad-spectrum pesticides on the cash crop, which helps preserve natural enemies and helps prevent resurgence of the primary pest population, secondary pest outbreaks and additional spraying to solve these man-made problems. Trap cropping means using very attractive plants growing in the perimeter of the garden or cucurbit field. Trap cropping is a unique pest prevention system that uses insect behavior to deter pest feeding. also reduced squash vine borer infestation on the unsprayed summer squash If DBM or other caterpillar populations exceed action thresholds in the main crop and insecticide applications are required, it is recommended to alternate between selective products that spare the beneficials, like spinosad (SpinTor),Bacillus thuringiensis aizawai(XenTari) or neem (Neemix). Prune or remove the trap crops once the pest population is high, otherwise they will serve as the breeding ground and the pests will attack the rest of your farm.
