Problems solved by technology

[0002] Cotton Fusarium wilt is one of the crop diseases with the highest susceptibility rate of cotton, no specific pesticides for treatment and control, and the greatest impact on cotton production. It can reduce cotton production by 40%-60%. Severely diseased fields can cause no harvest. Huge manpower, Physical strength, but the effect is not very obvious
The Ministry of Agriculture mainly recommends copper preparations and benzimidazole fungicides for prevention and treatment. Because cotton Fusarium wilt fungi are highly resistant and tolerant to these agents, the actual therapeutic effect is not great

Abstract

The invention discloses a pesticidal composition for treating fusarium wilt of cotton, which consists of the following raw materials in percentage by weight: 0.5 to 1.2 percent of 98 percent 3-indoleacetic acid, 0.2 to 0.6 percent of 50 percent naphthalene acetic acid, 1 to 3 percent of salicylic acid, 2 to 6 percent of plant activator protein, 35 to 59 percent of 40 percent acetic aldehyde and 35 to 59 percent of 55 percent white spirit. The pesticidal composition has the advantages of completely killing fusarium wilt bacteria within 30 minutes, stabilizing diseased plants without deterioration, beginning to recover the growth within five days, recovering within 8 to 12 days, controlling the recovery rate in a range from 85 to 93.5 percent and controlling the recurrence rate to be less than 11.5 percent.

Description

technical field [0001] The invention relates to a pesticide composition for treating cotton fusarium wilt and a preparation method thereof. Background technique [0002] Cotton Fusarium wilt is one of the crop diseases with the highest susceptibility rate of cotton, no specific pesticides for treatment and control, and the greatest impact on cotton production. It can reduce cotton production by 40%-60%. Severely diseased fields can cause no harvest. Huge manpower, Material strength, but the effect is not very obvious. The Ministry of Agriculture mainly recommends copper preparations and benzimidazole fungicides for prevention and treatment. Because the fungus of Verticillium wilt of cotton is highly resistant and tolerant to these agents, the actual therapeutic effect is not great. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, to provide a pesticide composition for the treatment of cotton Fusarium...
