Embodiment 1

[0020] Example 1 : 40% boscalid·hymexazol suspension concentrate.

[0021] Boscalid 30%, hymexazol 10%, sodium methylnaphthalenesulfonate formaldehyde condensate (dispersant) 5%, 0203B (surfactant) 6%, white carbon black (filler) 5%, silicic acid Magnesium aluminum (suspending agent) 0.4%, ethylene glycol (antifreeze) 3%, tributyl phosphate (defoamer) 1.5%, deionized water to make up to 100%. The above raw materials are mixed, dispersed by high-speed shearing, and ground with a sander to prepare a 40% boscalid·hymexazol suspension.

[0022] The above-mentioned 40% boscalid·hymexazol suspension was used to prevent and control cucumber wilt, and the cucumber was diluted with water to 800 times of liquid 7 days after transplanting and applied to the roots. The control effect was 92.7% 7 days after the application. Using 70% hymexazol wettable powder 1400 times liquid and 50% boscalid water dispersible granule 500 times liquid as control agents, the same method was used to apply...

Embodiment 2

[0023] Example 2 : 60% boscalid·hymexazol water dispersible granules.

[0024] Boscalid 15%, hymexazol 45%, sodium lauryl sulfate% (wetting agent), hydroxymethyl cellulose (dispersing agent) 5%, bentonite (disintegrating agent) 3%, polyethylene glycol Alcohol (binder) 2%, gum arabic (stabilizer) 1%, white carbon black to make up to 100%. Dry pulverize, granulate, dry, and sieve the above formula in proportion to obtain 60% boscalid·hymexazol water-dispersible granules.

[0025] The above-mentioned 60% boscalid·hymexazol water dispersible granules were used to control cucumber wilt, and the cucumber was diluted with water to 1000 times of water 7 days after transplanting and sprayed on the roots. The control effect was 95.2% 7 days after the application. Using 70% hymexazol wettable powder 1400 times liquid and 50% boscalid water dispersible granule 500 times liquid as control agents, the same method was used to apply the pesticides, and the control effects were 83.7% and 85...

Abstract

The present invention relates to a bactericidal composition of boscalid and hymexazol, the active ingredient is composed of boscalid and hymexazol, and the mass-number ratio of boscalid and hymexazol in the composition is 1: 3~5:1. The fungicidal composition of the invention is suitable for controlling cucumber wilt. The bactericidal composition of the invention has obvious synergistic effect, remarkable control effect on cucumber wilt, is easy to use, and has extremely strong operability and practical application value.

Description

technical field [0001] The invention relates to the field of pesticide preparations, in particular to a bactericidal composition of boscalid and hymexazol, which is used for preventing and treating cucumber wilt. Background technique [0002] Fusarium wilt usually occurs after flowering and fruiting. The damaged plants initially manifested as part of the leaves or one side of the plant wilting and drooping at noon, as if lacking water. Sooner or later, the wilting leaves continued to increase and gradually spread throughout the whole plant. Sooner or later, they could not recover. , and soon dies. The base of the main vine of the diseased plant is split longitudinally, and the diseased stem is cut longitudinally, and the vascular bundles can be seen to turn brown. Yellow-brown streaks appear at the base of the stem, nodes and internodes, often with yellow jelly flowing out. When wet, a white to pink mold layer is formed on the surface of the diseased part, and the diseased ...
