Using method of anti-disease composition of corn ear conidia

Abstract

The invention discloses a using method of an anti-disease composition of corn ear conidia. The using method comprises the following steps: A, preparing an original liquid which comprises 12% triadimefon wettable powder, 10% polyethylene glycol, monopotassium phosphate, artemisinin, indirubin, carboxymethyl cellulose sodium, oxalic acid and 5% aluminum sulfate; B, cultivating corn: selecting disease-free corn seeds, soaking the corn seeds by the original liquid in a 400 times in volume ratio for 1.5-2 hours, and taking out the corn seeds, washing the corn seeds by clean water, and drying the corn seeds in the sun, accelerating germination and seeding; C, during disease, adding water into the original liquid to be diluted to 600 time liquid for spraying work; and C, while spraying, adding water into the original liquid to be diluted to 500 time liquid for root irrigating operation. The using method disclosed by the invention is simple, and the used product is simple in using method, simple in proportion, convenient to use and good in northern leaf spot treatment effect. Tests show that 400-600 time liquid of the mixture has an obvious inactivating effect on conidiophore and conidia of pathogenic bacteria, and is good in sterilizing effect.

Description

Technical field: [0001] The invention relates to a medicine for vegetables, in particular to a method for using a disease-resistant composition of corn ear conidia. Background technique: [0002] The causative bacteria of round spot disease on corn ears are conidia. The diseased grains are dry and rotten, and the grains can be turned into powder by hand twisting. Bract leaves are infected with unshaped spots, some of which are dark brown, and generally do not form a black mold layer. The germs extend from the bract leaves to the inside of the ears, damaging the grains and cobs. The leaves are infected with water-soaked light green to yellow small spots at the beginning, which are scattered, and then expand into round to oval ring spots. The center of the lesion is light brown, the edge is brown, and the periphery has a yellow-green halo. The size is 5-15×3-5 (mm). Sometimes long linear spots are formed, and a black mold layer is also born on the surface of the lesion. ...
