Application of pesticide composite containing uniconazole and prodiamine as tobacco bud-restraining agent

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.
