The field experiment was carried out during the summer season of 2021-2022 to study response different weed management practices on growth and yield black gram. Cyperus sp., Phyllanthus niruri, Trianthema portulacastrum, Amaranthus viridis were dominant weeds. It observed that besides free treatment lowest count, dry weight weeds (3.66 g m-2), index (2.73%) as well highest control efficiency (6...

The main objective of this study was to evaluate the performance of a model for simulating the uptake of various pesticides on passive air samplers (PAS). From 2006-2007 a series of PAS using XAD-resin were deployed at Egbert, a rural agricultural site in southern Ontario, Canada, to measure the uptake of pesticides for time periods ranging from two months to one year. A continuous increase in ...

The species Rottboellia exaltata L. (itchgrass) has become an important weed in cultivated areas, requiring management studies to enhance its control. This study aimed evaluate the effectiveness of herbicides pendimethalin (1200 g ha−1), clomazone (1000 indaziflam (100 and trifluralin (900 ha−1) applied pre-emergence association with diquat (400 glyphosate (1175 addition their isolated applicat...

The carry-over effect of sub-lethal herbicides was investigated on the germination of seeds collected from surviving Chenopodium album plants, which had received 1/8, 1/8 twice, 1/8 three times, 1/4, 1/2, 1/1 doses of either pre-emergence ioxynil or post-emergence bentazone in a previous onion (Allium cepa) crop. Seeds were also collected from surviving C. album plants, which had received 1/4, ...

Pendimethalin herbicide toxicity to rice plants and barnyard grass invasion have increasingly affected the productivity of direct-seeded (DSR) in fields. Whether how promote DSR sustain weed management depend on appropriate pre-emergence application rate minimise its ecosystem. Pot experiments were conducted determine effects pendimethalin rates (1.5, 1.75, 2.0 kg a.i. ha−1, two control treatme...

A field study was conducted in the boro season of 2011-12 and aman season of 2012 at Jessore, Bangladesh, to evaluate the performance of sequential applications of preemergence herbicides (oxadiargyl 80 g ai ha(-1), pendimethalin 850 g ai ha(-1), acetachlor + bensulfuranmethyl 240 g ai ha(-1), and pyrazosulfuron 15 g ai ha(-1)) followed by a postemergence herbicide (ethoxysulfuron 18 g ai ha(-1...

In the Atlantic Coastal Plain region of southern Georgia (USA), cotton (Gossypium hirsutum L.) acreage increased threefold in the past decade. To more effectively protect water quality in the region, best management practices are needed that reduce pesticide runoff from fields in cotton production. This study compared runoff of two herbicides, fluometuron [N,N-dimethyl-N'-[3-(trifluoromethyl)-p...

Citrus (Citrus spp.) is one of the most important crops in Florida agriculture. Weed control is a major component in citrus production practices. If not controlled, weeds may compete with citrus trees for nutrients, water, and light and may also increase pest problems. Herbicides are an important component of integrated weed management program in citrus. Saflufenacil, a new herbicide registered...

Switchgrass (Panicum virgatum L.) is typically slow and difficult to establish. Field experiments evaluated switchgrass establishment and the response of warm-season grass weeds (large crabgrass [Digitaria sanguinalis (L.) Scop.], broadleaf signalgrass [Urochloa platyphylla (Munro ex C. Wright) r.D. Webster], Johnsongrass [Sorghum halepense (L.) pers.], and Texas panicum [Urochloa texana (Buckl...
