METHOD OF STIMULATION OF CEREAL AND LEGUMINOUS CULTURE GROWTH Russian patent published in 1995 - IPC

FIELD: agriculture. SUBSTANCE: thiadiazole derivatives of the general formula where R₁-H, CH₃, C₂H₅, C₃H₇,C₆H₅,C₆H₄OH, where n = 0 or 1; R₃ and R₄-H, Cl, OCH₃ were used as active substance at the dose 0.2-0.5 kg/ha for treatment of vegetating plants and at the dose 150-200 g/t at presowing seed treatment. Tests were carried out in pea, wheat and corn. Pea and wheat seeds were soaked as 150-200 g active substance per 1 t seeds. Maize is treated at the phase of natural 3-4 leaves with solution of active substance at the dose 0.2-0.5 kg/ha. Productivity of pea is increased by 0.8-3.8 c/ha and that of wheat - by 1.6-2.9 c/ha as compared with effect of 2-amino-[N-2-chlorophenylsulfonyl)-aminocarbonyl]-6-chlorobenzothiazole. Productivity of corn for silage is increased by 33-125 c/ha. EFFECT: increased productivity. 3 tbl
