Influence of living and non-living habitat complexity on arthropods in strip-tilled cabbage fields
… was conducted examining the effects of herbicide intensity and oat kill date on arthropods, weeds, and crop yield. Reduced herbicide intensity was associated with 1) lower abundance of several key cabbage pests and, 2) greater abundance of important natural enemy species. Habitats with …

The influence of application timing and soybean (Glycine max L.) canopy on imazethapyr efficacy
… possibility of combining narrow row spacings and reduced herbicide rates in no-tillage systems shows promise (DeFelice et al., 1989). However, the issues of the appropriate herbicides to use, proper application timings, and the size of the weeds at the times of application become important factors …

THE INFLUENCE OF CARRIER WATER QUALITY, COAPPLIED FOLIAR FERTILIZER, AND WATER CONDITIONING ADJUVANT ON HERBICIDE EFFICACY
Water is the primary carrier for herbicide applications; therefore, carrier water quality factors such as pH, hardness, temperature, or turbidity could be critical for influencing herbicide performance. Currently, there is no information on the effect of carrier water temperature on herbicides …

Herbicide combinations for establishing no-till soybeans (Glycine max) with an emphasis on the use of chlorimuron
… acid] were the most effective herbicides for horseweed (Conyza canadensis (L.)Cronq.) control prior to establishing full-season no-till soybeans (Glycine max (L.)Merr.). In greenhouse experiments, emergence of tobacco (Nicotiana tabacum L.) seedlings was severely inhibited by …

Canada thistle (Cirsium arvense [L.] Scop.) response to mowing, herbicide, competitive grasses, and soil amendments on wetland, upland, and mesic sites
… a significant challenge for land managers. Herbicide application can be effective, but mixed results, toxicity concerns, and the need for re-application demand new, more efficient strategies that reduce herbicide use. A greenhouse study tested effectiveness of clipping and grass seeding for …

Distinct biochemical and molecular mechanisms confer resistance to mesotrione and atrazine in a multiple herbicide-resistant waterhemp population
… partly due to multiple mechanisms for herbicide resistance. Previous research reported the first case of resistance to mesotrione and other 4-hydroxyphenylpyruvate dioxygenase (HPPD) herbicides in a waterhemp population designated MCR. Experiments were conducted to determine if …

Potential for site specific management of Lolium rigidum (annual ryegrass) in Southern Australia.
… to increase farmers’ financial returns through reduced herbicide costs while maintaining weed control in commercial paddocks near Bute and Tarlee, SA. Commercially available sensors N-Sensor, Greenseeker, Crop Circle and digital RGB camera were assessed for their ability to detect annual …

Managing Cereal Rye Living Mulch in Snap Beans with Chemical Mowing and Preemergence Herbicides
… establishment. Micro-rates of quizalofop-p-ethyl herbicide applied postemergence limited cereal rye living mulch vigor via chemical mowing; the dose response depended upon rye stage at application. Chemical mowing failed to preserve snap bean yield and consistently limit weed biomass. Split and …
