Results of studying the Flex and Fusilade Forte herbicides aftereffect used in soybean crops in the south of the Far East

The purpose of the study is to determine the sensitivity of a number of crops to the residual amount of successive applications of Flex 1.5 l/ha and Fusilad Forte 1.5 l/ha herbicides in soybean crops. The studies were carried out in 2020-2021 in the Far Eastern Research Institute of Plant Protection in the conditions of a growing house using the method of biological indication of soil stocks of herbicides (determination of volumetric phytotoxicity of the area). The seeds of the tested crops were sown in meadow-brown podzolized soil, especially after harvesting soybeans treated with herbicides in the phase of two trifoliate leaves. During the growing season, test cultures recorded all signs of damage and inhibition of plants by residual amounts of herbicides. After cutting the experimental plants to reduce their wet aboveground weight and height compared to the control (without the use of herbicides), final conclusions were made about the degree of toxicity for the tested crops of herbicide residues and their active metabolites preserved in the soil. According to the reduction in plant mass, as the most objective criterion for assessing the phytotoxicity of herbicides, the crops were arranged in order from the most sensitive to the most resistant as follows: tomatoes function show_eabstract() { $('#eabstract1').hide(); $('#eabstract2').show(); $('#eabstract_expand').hide(); }
