Problems solved by technology

[0002] Cucumber wilt [Fusarium osysporum (Schl.) f.sp.cucumerinumOwen] mainly affects cucumber, Cucurbitaceous crops such as loofah, watermelon, melon, gourd, wax gourd, etc. are caused by Botrytis cinerea, and the disease occurs successively after the cucumber blooms. The damaged plants initially show that some leaves or one side of the plant wilt and droop at noon, as if lacking water. In the future, wilting leaves will continue to increase, gradually spread throughout the whole plant, and will die soon, resulting in reduced yield.

Embodiment 1

[0012] Embodiment 1 Preparation of active ingredient content is 30% wettable powder or water dispersible granule

[0013] The specific ratio is:

[0014] Raw material dosage (parts by weight)

[0015] Carbendazim 10

[0016] Hymexazol 10

[0017] garlic oil 10

[0018] Wetting agent 7

[0019] Fillers make up to 100

[0020] The preparation method includes: weighing carbendazim, hymexazol, garlic oil, wetting agent, filler (white carbon black, kaolin, diatomaceous earth), first using white carbon black to absorb the garlic oil, mixing evenly, and then Jet milling is prepared into a wettable powder with an active ingredient content of 30%. Wettable powders can be prepared into water-dispersible granules by granulation.

Embodiment 2

[0021] Embodiment 2 Preparation of wettable powder or water dispersible granule with active ingredient content of 40%

[0022] The specific ratio is:

[0023] Raw material dosage (parts by weight)

[0024] Carbendazim 20

[0025] Hymexazol 10

[0026] garlic oil 10

[0027] Wetting agent 7

[0028] Fillers make up to 100

[0029] The preparation method includes: weighing carbendazim, hymexazol, garlic oil, wetting agent, filler (white carbon black, kaolin, diatomaceous earth), first using white carbon black to absorb the garlic oil, mixing evenly, and then Jet pulverization is prepared into a wettable powder with an active ingredient content of 40%. Wettable powders can be prepared into water-dispersible granules by granulation.

Embodiment 3

[0030] Embodiment 3 Preparation of active ingredient content is 50% wettable powder or water dispersible granule

[0031] The specific ratio is:

[0032] Raw material dosage (parts by weight)

Abstract

The invention discloses a soil bactericide pesticide composite. The active ingredients of the pesticide composite comprise the following substances in percentage by weight: 5-30% of carbendazim, 5-20% of hymexazol, 5-20% of garlic oil and the balance of additive and filler. Through the combination of the carbendazim, the hymexazol and the garlic oil, the bactericidal effect of the soil bactericide pesticide composite is improved, the efficiency is increased, the drug resistance is delayed, the dosage of chemical synthetic drugs is reduced, and the efficiency is significantly increased because the garlic oil has high bactericidal power and strong fumigating and sterilizing function on soil. By adopting the pesticide composite capable of preventing and curing wilt of vegetables such as cucumber, the preventing and curing effect of wilt can be improved, the drug resistance of pathogenic bacteria can be delayed, and the preventing and curing cost can be reduced.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a soil fungicide pesticide composition and its application. Background technique [0002] Cucumber Fusarium [ Fusarium osysporum (Schl.) f.sp. Cucumerinum Owen] mainly harms Cucurbitaceae crops such as cucumber, loofah, watermelon, muskmelon, gourd, winter melon, etc. It is caused by Botrytis cinerea, and the disease occurs successively after the cucumber blooms. The damaged plants initially show that some leaves or one side of the plant wilt and droop at noon , like lack of water, and then the number of wilting leaves will continue to increase, gradually spread throughout the whole plant, and die soon, resulting in reduced yield. With the development of vegetables in greenhouses, greenhouses and other facilities, especially the occurrence of Fusarium wilt in protected lands for many years has become more and more serious. Contents of the invention [0003] The object of the pres...
