Problems solved by technology

However, after topping and wiping the buds, the axillary buds grow rapidly, seriously affecting the yield and quality of tobacco leaves
Therefore, it is still necessary to manually smear the buds for 2-3 times, which is not only labor-intensive and troublesome, but also cannot control the growth of axillary buds in time.
The emergence of tobacco sprout inhibitors can overcome the above shortcomings, but the currently used sprout inhibitors 12.5%, 25% flumethalin EC, 33% pendimethalin EC, and 36% secbutaline EC have a low dilution factor. The disadvantages of high cost, potential safety hazards in storage and transportation, and environmental pollution

Abstract

The invention relates to a pesticide composition, in particular to a pesticide composition comprising chlorpropham and uniconazole. The percentage by weight of the chlorpropham and the uniconazole is (60:2)-(20:10) and is preferably (30:2)-(4:2). The pesticide composition is used as a tobacco bud inhibitor, inhibits the growth of tobacco axillary buds, and has the characteristics of being high in control effect, low in toxicity, easy to store, safe in transportation and free of environmental pollution. After the pesticide composition is diluted to 300 and 400 times, the control effects are respectively 95.01 percent and 94.52 percent. The pesticide composition is the ideal substitute of all missible oil type tobacco bud inhibitors at present.
