METHOD OF DETERMINING FUNGICIDES WITH MINIMUM VALUE OF TOTAL INHIBITION OF DEVELOPMENT OF SEEDS OF GRAIN CROPS WHEN SOWING ON SPECIFIC SOILS

摘要

FIELD: agriculture.;SUBSTANCE: invention relates to agriculture, in particular to plant growing. Method includes formation of at least two treated fungicides, test samples of seeds of grain crops and one untreated control sample of seeds of cereal crops, ensuring contact of experimental treated seeds samples with soil with addition of water till minimum moisture content of soil is achieved; providing contact of control sample of seeds with sand with addition of water till minimum moisture capacity of sand is achieved; holding said test and control samples of seeds until sprouting, removing soil and sand from sprouted seeds and placing cleaned test and control samples of sprouted seeds in identical transparent containers with water, compaction of sprouted seeds in containers by means of vibration action in vertical plane and subsequent impact action on vessel bottom, at that, after vibrating action on samples of seeds in vessel identical masses are placed, determination of bulk volumes of experimental (V2_i) and control (V3) samples of sprouted seeds by height of cargo location from bottom of capacity, determination of total inhibition value for each sample (I_i) by formula: I_i=((V3-V2_i)/(V3-V1))*100 %, where V1 – correction factor, characterizing bulk volume of swollen seeds of cereal grains, sprouting which was carried out for 24 hours; V2_i – bulk volume of sprouted seeds of prototype; V3 – bulk volume of sprouted seeds of control sample, i – serial number of prototype, determination of minimum I_i, from which the test sample is analyzed, treated with a fungicide with a minimum value of total inhibition.;EFFECT: ensuring reliability of obtained results owing to possibility of increasing the volume of statistical sampling.;10 cl, 6 dwg, 3 tbl, 5 ex
