Problems solved by technology

However, flumethamine alone can cause phytotoxicity such as deformity of young leaves of upper nodes, insufficient expansion, mesophyll necrosis, petiole breakage of middle / upper leaves, rooting disorder of adventitious roots, necrosis, etc.
What's more serious is that the wounds at the base of petioles caused by pesticide damage can induce hollow disease, sclerotinia, gray mold and other diseases, which will have a negative impact on the yield and quality of tobacco leaves

Embodiment 1

[0054] Example 1 50% flumetriamine + 5% prohexadione calcium suspension

[0055]

[0056] Active components, dispersant, wetting agent, water and other components are uniformly mixed according to the proportion of the formula, and after grinding and / or high-speed shearing, a suspension concentrate of 50% flumethamine + 5% prohexadione calcium is obtained.

Embodiment 2

[0057] Example 2 50% flumetriamine + 2.5% prohexadione calcium wettable powder

[0058]

[0059] The active ingredient, various additives and fillers are mixed according to the proportion of the formula, and after being pulverized by an ultra-fine pulverizer, a wettable powder of 50% flumetriamine + 2.5% prohexadione calcium is obtained.

Embodiment 3

[0060] Example 3 24% flumethamine + 2% prohexadione calcium water emulsion

[0061]

[0062] Add active ingredients, solvents, and emulsifiers together to dissolve into a uniform oil phase; mix water-soluble components with water to prepare a water phase; mix the oil phase with water under high-speed stirring to obtain 24 The aqueous emulsion of % flumethamine + 2% prohexadione calcium.

Abstract

The invention relates to a tobacco axillary bud inhibitor and a method for suppressing tobacco axillary buds. The tobacco axillary bud inhibitor contains flumethamine and prohexadione calcium as active ingredients, and the combined use of flumethylene and prohexadione calcium shows synergistic effect Tobacco axillary bud inhibition effect, long-term inhibition of tobacco axillary bud germination and growth at low application doses, and no obvious phytotoxicity to tobacco stems and leaves was observed.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a tobacco axillary bud suppressor and a method for suppressing tobacco axillary buds. Background technique [0002] Each leaf axil of tobacco has axillary buds, and all axillary buds can germinate into branches and bloom. After topping, the apical dominance is removed, and the axillary buds germinate rapidly and consume a lot of nutrients, which affects the yield and quality of tobacco leaves. Therefore, topping and bud stroking is an important measure to increase the yield and value of tobacco leaves. However, the traditional manual sprouting is labor-intensive and troublesome, and it is not timely and thorough, which can easily cause clusters of smoke branches, fireworks, and infectious diseases. [0003] Since the 1940s, countries all over the world have been researching and promoting chemical agents to suppress tobacco axillary buds. For example, maleic acid hydrazide or its sal...
