Abstract

The invention relates to pesticide composite containing synergistic effective dose of uniconazole and prodiamine as a tobacco bud-restraining agent. The weight ratio of the uniconazole to the prodiamine is 1: 80 to 10:20, preferably, 1: 40 to 5:70, and most preferably, 2:60 to 2:70; the inhibition effect of the composite after being applied for 2, 4 and 6 weeks is better than that of each single dose such as 48% of ammonia trifluralin cream, 5% of uniconazole wettable powder and 36% of butralin cream; the effect is equal to that of the artificial interruption, so that lots of labor is saved. The pesticide composite also relates to a method and an application of the composite for inhibiting tobacco axillary bud from growing.

Description

technical field [0001] The invention relates to a synergistic pesticide composition comprising uniconazole and amfluralin. The composition is used as a tobacco bud suppressant. It belongs to the technical field of plant protection. Background technique [0002] Amfluralin: English common name: Trifluralin. Structural formula: [0003] [0004] The chemical name is 2,4-dinitro-N3,N-dipropyl-6-trifluorotoluene-1,3-diamine. Molecular formula C 13 h 17 f 3 N 4 o 4 ; The molecular weight is 350.3. [0005] Amfluralin, characterized by yellow columnar crystals, melting point 122.5-124°C, burning point 198°C, PH6-8, density 1.41 (25°C), stability: moderately stable to light, stable to acid, alkali and heat. [0006] Amfluralin water dispersible granules are yellow granules in appearance, active ingredient content is 55-65%, water content is ≤2.5, pH6-8, dispersibility is ≥85%, wetting time is ≤90s, and suspension rate is ≥75%. [0007] Amfluralin. Rat (male / female) a...
