Embodiment Construction

[0020] Below by example the present invention is described in further detail:

[0021] According to the conventional processing method, the original medicine of dicamba is processed into:

[0022] 40% soluble liquid (single dose),

[0023] 9% imazaba · uniconazole (7:2 composition) microemulsion,

[0024] 15% dicamba·flumezamine (2:13 composition) water dispersible granules,

[0025] Conduct field trials.

[0026] Since dicamba is a new tobacco bud suppressant of the present invention, whether it has adverse effects on the yield and quality of tobacco, this test has carried out production and quality inspections on dicamba. The test method of the present invention is further described below.

Abstract

The invention relates to applications of pesticide active ingredient dicamba in inhibiting tobacco axillalry bud growth or in preparing a tobacco bud inhibitor. The invention also discloses a composition comprising another pesticide active component, wherein the pesticide active component is selected from uniconazole, trifluralin, prodiamine, flumetralin, pendimethalin, and butralin; and the weight ratio of dicamba to the pesticide active component ranges from 1:60 to 60:1. The pesticide active component can be made into a soluble liquid preparation, a micron emulsion, a water emulsion preparation, a suspending agent, a water dispersible particle preparation, a microcapsule preparation, a wettable powder, a missible oil, and the like. It is confirmed by experiments that the composition is used for inhibiting bud growth, and bud growth inhibiting effect is excellent, wherein dicamba is taken as the main active ingredient, and the composition is prepared from dicamba, the pesticide active component, and an auxiliary agent; no adverse influence on tobacco leaf chemical composition is caused by application of 40% of dicamba soluble liquid preparation, potassium content is increased, and tobacco leaf quality is improved.
