Abstract

The main directions of research on chemical means of protecting fodder crops from diseases, pests and weeds in the field fodder production of the All-Russian Fodder Research Institute are given. Studies on toxicological assessment of feed and soil are given. Plant Protection Department included three laboratories: the Herbicide Laboratory, the Plant Protection Laboratory and the Feed Toxicological Evaluation Laboratory. The Laboratory of Herbicides was established in 1967 to conduct research on the chemical method of controlling weeds on fodder crops, hayfields and pastures. Research on the study of pests of fodder crops was started in 1939 in the newly created laboratory for the protection of fodder crops from pests and diseases. The Feed Toxicology Assessment Laboratory was established in 1980 to assess pesticide residues in crop and soil. As a result of the studies, a system of measures for clover from pests has been developed; alfalfa diseases and pests and measures to combat them in the Non-Chernozem zone were studied. Pests and pathogens of corn, root crops, peas, lupine and other fodder crops were identified; their biology, ecology and harmfulness have been studied. A set of protective measures has been developed to combat the main pests and diseases of fodder crops, including soil cultivation techniques, early sowing dates, the use of resistant varieties, micro- and macrofertilizers, pre-sowing treatment of seeds with combined preparations, etc. Plant Protection Department carried out work with herbicides. As a result of research begun in 1950, a method was developed to clean the meadows from weedy herbaceous vegetation with the help of preparations 2,4-D and 2M-4X. A chemical method for the destruction of woody and shrubby vegetation with the help of the same preparations in the Non-Chernozem zone of the European part of the USSR has been developed. Methods of using herbicides on crops of almost all fodder crops have been developed: perennial and annual legumes and cereal grasses for green mass and seeds, corn, fodder beets, rapeseed, etc. The theoretical issues of the mutual influence of fodder crops and weeds are studied, the substantiation of the effectiveness of the use of herbicides on different types of soils is given.
