Several abiotic and biotic stresses can affect soybean in a growing season. Heterodera glycines, soybean cyst nematode, reduces yield of soybean more than any other pathogen in the United States. Field and greenhouse studies were conducted to determine whether preemergence and postemergence herbicides modified the reproduction of H. glycines, and to determine the effects of possible interactive...

Soybean is an important crop worldwide. Soybean cultivars differ in their sensitivity to soil salinity and herbicide damage. In these experiments, we examined the impact of salinization and herbicide (imazethapyr and chlorimuron) application on the growth and yield of two soybean cultivars, Essex and Manokin. Experiments were conducted in small pots in the greenhouse, in outdoor sand cultures, ...

Imazethapyr (IM) is a widely used chiral herbicide that inhibits the synthesis of branched-chain amino acids (BCAAs). IM is thought to exert its toxic effects on amino acid synthesis mainly through inhibition of acetolactate synthase activity, but little is known about the potential effects of IM on other key biochemical pathways. Here, we exposed the model plant Arabidospsis thaliana to trace ...

Glyphosate-resistance evolution in weeds is evident globally, especially in areas where transgenic glyphosate-resistant crops dominate. Resistance to glyphosate is currently known in 16 weed species, including rigid ryegrass in Australia. Following the first report of glyphosate resistance in 1998, there are now 78 documented glyphosate-resistant populations of rigid ryegrass in grain-growing r...

Cerrado biodiversity has been threatened by the increase in agricultural production state of Tocantins and use pesticides. This work was carried out Formoso do Araguaia region, on banks River, which is home to about 1,825 indigenous people one largest lands Tocantins, Brazil. The presence pesticides imidazolinone strobirulin classes verified, analyzed UHPLC-MS/MS from April 2018 February 2019, ...

O controle de plantas daninhas infestantes na soja torna-se prática importante para evitar perdas produtividade grãos. Diante disso, objetivou-se avaliar a seletividade e eficácia herbicidas pré-emergentes associados ou não ao glyphosate aplicado em pós-emergência da cultivar DM 57i52. experimento foi conduzido delineamento blocos casualizados, com quatro repetições. Foram testados 15 tratament...

An investigation on “Weed Management and Crop Growth Modeling in Soybean” was carry out red sandy loam soil at UAS, Main Research Station, Hebbal, Bangalore during Rabi 2010 (September to December). The weed control practices included the study were i) Pendimethalin 30 EC 1.0 kg a.i./ha – 3 days after sowing, ii) Imazethapyr 10 SL 100 g 20 iii) Quizalofop-p-ethyl 5 50 iv) Chlorimuron ethyl 25 W...
