The purpose of the research is to study the effectiveness of zeolite as a carrier of a soil-active herbicide in the fallow field of a nursery. The experiment used zeolite from the Sakhaptinskoye deposit in the Krasnoyarsk Territory. Mineral fraction is 1-3 mm. The zeolite was enriched with the soil-active herbicide Fabian, VDG (imazethapyr + chlorimuron) , which is active against annual and some perennial dicotyledonous and annual cereal weeds in soybean crops. Since the State Catalog of Pesticides and Agrochemicals approved for use on the territory of the Russian Federation does not contain soil-active herbicides for the protection of garden crops, in the Fabian experiment, VDG was tested in the fallow field of a nursery. Experimental options included: control (without herbicide treatment) and experimental options: Fabian, VDG, 0.08 l/ha; Fabian, VDG, 0.09 l/ha; Fabian, VDG, 0.1 l/ha; Zeolite + Fabian, VDG, 0.08 l/ha; Zeolite + Fabian, VDG, 0.09 l/ha; Zeolite + Fabian, VDG, 0.1 l/ha. The applied preparations were incorporated into the soil by harrowing. The level of initial contamination of the fallow is average, the type of contamination is mixed with the dominance of annual dicotyledonous weeds (upturned acorn grass, common chickweed, common barnyard grass). Accounting for the biological effectiveness of the herbicide, carried out 30 days after its application, showed a reduction in the number of weeds by 87,0% (Fabian, VDG, 0.1 l/ha; zeolite + Fabian, VDG, 0.08 l/ha) - 94,6% (zeolite + Fabian, VDG, 0.09 l/ha). The effectiveness of the combined use of zeolite and herbicide at a dose of 0.09 l/ha and 0.1 l/ha is higher compared to options for spraying the soil with the pesticide in its pure form.
