Dynamics of Clomazone Formulations Under Different Applications Conditions [PDF]

Planta Daninha, 2019
ABSTRACT: Maintenance of straw on the soil surface in sugarcane production areas can influence weed occurrence and herbicide dynamics. After application, considerable losses of clomazone can occur as a result of its physicochemical characteristics. For this reason, novel formulations have been developed.

Greater Resistance to Drought‐Induced Embolism Is Linked to Higher Yield Maintenance in Soybean

Plant, Cell &Environment, Volume 49, Issue 7, Page 4027-4040, July 2026.
ABSTRACT With increasing drought events worldwide, crop breeding must focus on drought resistance to maintain crop yields. To ensure a high level of gas exchange and growth, plants need to maintain the integrity of their vascular system under drought conditions. While the impact of drought‐induced vascular damage on tree species is well‐documented, its

Scientific Opinion on waiving of the dog studies in the regulatory process of agrochemicals approval

EFSA Journal, Volume 24, Issue 7, July 2026.
Abstract Commission Regulation (EU) No. 283/2013 sets out the data requirements for pesticide active substances and includes short‐term oral toxicity testing in rodents (90‐day rat study) and non‐rodents (90‐day dog study) to support human health hazard assessment for pesticide active substances in the European Union (EU). However, the relevance of the

Performance of an S‐metolachlor capsule suspension for barnyardgrass control and crop tolerance in fenclorim‐treated rice

Agrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Barnyardgrass [Echinochloa crus‐galli (L.) P. Beauv.] is the most problematic weed of delayed‐flooded rice (Oryza sativa L.) systems in the mid‐southern United States. Recent findings suggest that acetochlor can achieve effective barnyardgrass control in rice, but rice injury can occur with rainfall soon after application.
