Embodiment 3

[0075] Embodiment 3, the control of apple tree spot defoliation disease

[0076] Mix 20g of tebuconazole, 5g of Zinc, 15g of sodium lignosulfonate, 4g of aluminum chloride, 1.5g of tributyl phosphate, 5g of pull-off powder, and kaolin to a total of 100g, and mix them with airflow , by kneading, granulating, drying, and sieving to make water-dispersible granules.

[0077] The prepared water dispersible granule is diluted by 2000-2500 times and sprayed on the apple trees with spot defoliation disease in the field, and the control effect in the field is 96.69% within 72 hours after spraying.

[0078] 10% tebuconazole water-dispersible granules and 30% zinc zinc water-dispersible granules were used in the same way as above, and the control effects were 43.86% and 44.6% respectively at 72 hours after treatment.

[0079] It can be seen that the control effect of the present embodiment is more than 1.5-2 times higher than that of the single agent of the mixed preparation.

Embodiment 4

[0080] Embodiment 4, the control of apple tree spot defoliation disease

[0081] Add 20.9g of tebuconazole, 26g of Zinc, 15g of sodium lignosulfonate, 4g of aluminum chloride, 1.5g of stabilizer tributyl phosphate, 5g of pull-off powder, and kaolin to a total of 100g, mix well, and press Tablets made into effervescent tablets.

[0082] The prepared effervescent tablet is diluted by 2000-2500 times and sprayed on apple trees with spotted leaf spot in the field, and the control effect in the field is 93.63% within 72 hours after the application.

[0083] 10% Tebuconazole Effervescent Tablet and 30% Zinc Effervescent Tablet were used according to the same method as above, and the control effects were 49.68% and 50.01% respectively at 72 hours after taking the medicine.

[0084] According to the control effect of the embodiment, it can be seen that the control effect of the mixed preparation is 1.5-2 times higher than that of the two single doses for the apple tree spot defoliati...

Embodiment 5

[0085] Embodiment 5, the control of apple tree spot defoliation disease

[0086] 10.9g of tebuconazole, 5g of Zinc, 15g of sodium lignosulfonate, 4g of aluminum chloride, 1.5g of tributyl phosphate, 5g of pull-off powder, and kaolin were added to a total weight of 100g and mixed, and then the mixture was placed Stir evenly in a stirring tank, and then mix evenly through a jet mill to make a wettable powder.

[0087] The prepared wettable powder is diluted by 2000 to 2500 times, sprayed on the apple trees with spotted defoliation in the field, and the control effect in the field is 93.90% within 72 hours after the application.

[0088] 10% tebuconazole wettable powder and 30% zinc zinc wettable powder were used according to the same method as above, and the control effects were 47.28% and 44.01% respectively at 72 hours after the medicine.

[0089] According to the prevention and control effect of the present embodiment, it can be seen that the control effect of the mixed prep...

Abstract

The invention provides a bactericidal agent composition with tebuconazole, which comprises two components of A and B, wherein the component A is tebuconazole, the component B is selected from metiram and myclobutanil or polyoxin. The bactericidal agent composition with tebuconazole of the invention has the advantages of overall acting system, evident efficiency-increasing effect and little medicine-consuming amount, does not generate drug resistance after being continuous used and is used for preventing and curing various crop diseases, in particular to the prevention and cure of fleck leaf cast of apple trees.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a fungicide composition containing tebuconazole. Background technique [0002] Tebuconazole: a triazole fungicide. It is a systemic fungicide with protective and therapeutic effects. It is an episterol biosynthesis inhibitor, which is safe for crops and has a good effect on the prevention and treatment of spotted leaf disease. However, there is only a single-dose product of tebuconazole in the market at present, and severe resistance has been produced after long-term use. [0003] Zinc: It is a protective agent for foliar spraying, which has a strong contact effect on many pathogens such as downy mildew, leaf spot and anthracnose. It is safe for plants, and the chemical properties of the active ingredients are relatively active. It is easily oxidized into isothiocyanate compounds in water. It has a strong inhibitory effect on the enzymes containing -SH groups in pathogenic bacteria, a...
