Abstract

The invention discloses a medicament for preventing and controlling wheat smut. The medicament is mainly prepared from the following components in parts by weight: 5 parts of carboxin, 1-5 parts of uniconazole, 2-6 parts of diniconazole, 0.2-0.6 part of imidacloprid, 0.4-0.8 part of fludioxonil, 20-30 parts of radix stemonae, 15-25 parts of areca nuts, 25-35 parts of fructus kochiae, 2-10 parts of chitosan, 0.1-0.5 part of sodium carboxymethylcellulose and 0.02-0.06 part of glycerin monostearate. Compared with the prior art, the medicament prepared by the invention has the advantages that the pesticide effect is prominent, the period of preserving effect is long, and the effect of preventing and controlling the wheat smut can be remarkably improved.

Description

technical field [0001] The invention relates to a wheat smut control agent, which is applied in the field of agriculture. Background technique [0002] Wheat smut mainly occurs on the ear, and the diseased ear is drawn out earlier than the healthy ear. Initially, the outside of the diseased spikelet was coated with a gray film, which ruptured after maturity and released black powder (chlamydospores of the pathogen). After the black powder was blown away, only the exposed cob remained. The spikelets on the diseased ears were all or partially destroyed, and only a few healthy ears remained on the upper part. When wheat is infected by Tilletia smut and Tilletia smut at the same time, Tillet smut appears on the upper part of the diseased ear and loose smut on the lower part. Smut also occasionally attacks leaves and stalks, where strips of black spore mounds grow. [0003] At present, there are many kinds of pesticides for the control of wheat smut, most of which need to be a...
