What is it? Honeyvine milkweed (Cynachum laeve) is a perennial, deciduous, vining member of the milkweed family Asclepiadaceae. It is native to the United States and can serve as a host for monarch butterfly larvae. Honeyvine milkweed tends to be more problematic in production systems with reduced or no tillage, including perennial fruits. It can…Read more about Honeyvine Milkweed[Read More]


Earlier this year, Rely® 280 was registered for use in transplanted cantaloupe, cucumber, pepper, summer squash, tomato, and watermelon with a supplemental label. The registration allows for the use of Rely® 280 for pre-plant burndown and post-directed applications to row middles. Previously, postemergence burndown and row middle options were limited to glyphosate (Roundup®), carfentrazone (Aim®),…Read more about Rely® 280 Added to Row Middle Weed Control Arsenal in Select Crops[Read More]


The most recent two podcast episodes of the Strawberry Chat focus on spring weed and disease management. Spring Weed Management Podcast Kevin Schooley and Stephen Meyers joined the discussion to talk about weeds and weed management in matted-row and plasticulture strawberry production. Steve spoke about weeds commonly seen in strawberry fields and gave us a…Read more about Strawberry Podcasts on Spring Weed and Disease Management[Read More]


Onions are poor competitors with weeds. Their narrow leaves do not compete well for light, and their shallow root system makes them poor competitors for water. Tight in-row and between-row plant spacing make mechanical weed control, including hand-weeding, difficult. Chemical weed control can be effective and reduce the amount of time required to hand-weed onions….Read more about Even Minimal Herbicide Use Can Reduce Hand-Weeding Time[Read More]


This questionnaire is part of a USDA Specialty Crop Research Initiative (SCRI)-funded proposal  (DEVELOPING A NATIONAL TEAM TO OPTIMIZE NON-HERBICIDE WEED MANAGEMENT TECHNIQUES IN COLE AND LEAFY GREEN CROPS) to identify grower interest in novel technology for weed management. Novel technology includes vision-guided sprayers/thinners, steam weeding, and precision mechanical, laser, and electric weeders. It may…Read more about New Questionnaire to Identify Grower Interest in Novel Weed Management Technology[Read More]


Attendees at a July field day at the Meigs Horticulture Research Farm in Lafayette, Indiana saw first-hand the potential of cover crops to suppress weeds in a SARE-funded demonstration plot. First, some background: Three cover crop species were sown with a ten-foot drill on September 10, 2021: Oats at 100 lb/acre Cereal rye at 65…Read more about Cover Crop Demonstration Plots Show Weed Suppression Potential[Read More]


Try as we might, it seems that no weed management program controls 100% of the weeds in a field. Inadequate or excessive rainfall can limit the success of preemergence herbicides. Less-than-ideal soil moisture can result in unsatisfactory in-season cultivation. Even when we have effective herbicide options, late emerging weeds often cannot be treated within the…Read more about Going Rogue[Read More]


Grass-selective herbicides are valuable to weed management in broadleaf vegetable crops. As harvest season draws closer, it is important to note that not all grass herbicides have the same pre-harvest interval (PHI) requirements. The two most commonly used grass-selective herbicides are clethodim and sethoxydim. While most PHI’s are similar between the two (Table 1), there…Read more about Keeping an Eye on Grass Herbicide PHI (Pre-Harvest Interval)[Read More]
