Problems solved by technology

However, in the application of conventional retardants such as paclobutrazol, uniconazole, chlormequat, biju, ethephon and other regulators, there have been many problems such as less and less obvious drug effects, larger doses, high residues, and high costs. Therefore, it is an urgent need for the current rice cultivation and production to study safe

Abstract

The invention discloses a composition of prohexadione calcium and a fungicide. The composition includes 5 to 50 parts by weight of the prohexadione calcium and 5 to 60 parts by weight of the fungicide; the bactericide is a triazole fungicide such as epoxiconazole, tebuconazole, hexaconazole and difenoconazole, or a carboxylic acid amide fungicide such as thifluzamide and fenoxanil, or a benzimidazole fungicide such as carbendazim and thiophanate-methyl, or an imidazole fungicide such as prochloraz and prochloraz-manganese chloride complex. The composition of the prohexadione calcium and the fungicide provided by the invention can achieve the purposes of vigorous growth control, disease resistance and yield increase, has no effect on next-stubble crops, reduces the pesticide costs of farmers, and increases the crop yield, so as to increase the income of farmers, and create enormous economic and social values.

Description

technical field [0001] The invention belongs to the technical field of pesticide preparation, and in particular relates to a composition of prohexadione calcium and a fungicide. Background technique [0002] Calcium prohexadione is a new type of plant growth regulator and a kind of plant growth retardant. It works by interfering with the final step of GA biosynthesis, namely blocking GA 12 Aldehyde to GA 8 The synthesis of GA hinders the activation process of GA, and increases the levels of ABA, zeatin and isopentenyl adenosine-type cytokinins. It has the effect of inhibiting vegetative growth, promoting reproductive growth, and achieving the purpose of increasing production and improving quality. Prohexadione calcium can shorten the stem length of many plants through foliar treatment. Compared with the currently widely used triazole retarders, prohexadione calcium has no residual toxicity to rotation plants, no pollution to the environment, and can also Promote plant nu...
