Environmental assessment of the use of the herbicide Lumax

The sensitivity of agricultural crops to the Lumax herbicide, consisting of three active agents C-metolachlor, terbutylazine and mesotrione, the duration of their action in meadow-brown soil, and the aftereffect of the herbicide on the plants of the crop rotation were determined. The study was conducted in the conditions of the greenhouse in the Primorsky Territory in 2019 and 2020. The herbicide Lumax was used on experimental plots before corn germination at doses of 4.0 l/ha (recommended) and 8.0 l/ha (twice the recommended). In the autumn of 2019 and in the spring of 2020, samples of meadow-brown soil were taken from the experimental plots and from the control (without herbicides) from the depth of the arable layer containing 3.5% humus. The samples were used to establish the duration of the action of active agents and the aftereffect of the herbicide Lumax. Prior to this, plants indicating residual amounts of the chemical in meadow-brown soil were preselected. The doses of the herbicide which reduce the above-ground mass of the test plant by 50% were calculated, as well as its maximum permissible concentration in the soil. It was determined that by the end of the growing season, 0.7–3.0% of the active agent of the herbicide Lumax is retained in meadow-brown soil at a rate of application of 4.0 l/ha, and 0.6–3.9% – at a rate of 8.0 l/ha. By the beginning of the next field season, the preparation applied at the recommended rate completely decomposed, while when it was applied at a double rate of the recommended rate, 0.8–1.7% of the herbicide remained. Eight months after the application at a rate of 4.0 l/ha, the herbicide Lumax is safe for subsequent crops of the crop rotation. In case of overdose or double application (8.0 l/ ha), it can have an aftereffect on sensitive crops. The crops that are highly sensitive to the Lumax preparation were identified: cabbage, radish, rapeseed, beetroot, tomatoes, cucumber and rice; sensitive: wheat, buckwheat and soybean; relatively resistant: oats and barley. A safe consumption rate of the Lumax herbicide (4.0 l/ha) for subsequent crops of the crop rotation was established.
