Embodiment 1

[0030] Processing and application of wettable powder: mix according to 7% flusilazole and 14% carbendazim, then add 2-6% dispersant, 2-5% wetting agent, make up the rest to 100% with carrier, It is processed into wettable powder according to the wettable powder process. For the prevention and treatment of banana scab, the spray is diluted 2500 times, and the control effect is 94.18%. If 4000 times of 20% flusilazole WP and 800 times of 50% carbendazim WP are used, the control effects are 93.21% and 88.34% respectively.

[0031] The above-mentioned dispersant is one of sodium alkylnaphthalene sulfonate or sodium lignin sulfonate; the wetting agent is one of sodium lauryl sulfate and pull-off powder; the carrier is light One of calcium or kaolin, white carbon black.

Embodiment 2

[0033] Processing and application of water-dispersible granules: mix with flusilazole 9%, carbendazim 12%, dispersant 1-8%, wetting agent 0.5-5%, binder 0.05-1%, disintegrant 6-10%, and the balance is made up to 100% with a carrier, mixed evenly, added an appropriate amount of water, granulated, dried, etc., and processed into water-dispersible granules according to the water-dispersible granule process. For the prevention and treatment of grape powdery mildew, it is diluted and sprayed by 2000 times, and the control effect is 95.25%. If 2500 times of 10% flusilazole water-dispersible granules and 800 times of 50% carbendazim water-dispersible granules are used, the control effects are 92.66% and 87.80% respectively.

[0034] The above-mentioned dispersant is one of sodium alkylnaphthalene sulfonate or sodium lignin sulfonate; the wetting agent is one of sodium lauryl sulfate and pull-off powder; the carrier is light One of calcium or kaolin, white carbon black; the binder is...

Embodiment 3

[0036] Processing and application of suspending agent: mix with flusilazole 5%, carbendazim 16%, dispersant 2-5%, wetting agent 0.5-3%, preservative 0.1-1%, antifreeze 2-8 %, 0.1-0.5% defoamer, 0.1-1% thickener, and make up the balance to 100% with water, and process it into a suspending agent according to the suspending agent process flow. For the prevention and treatment of black bean disease of grapes, it is diluted and sprayed by 2000 times, and the control effect is 94.86%. If 4000 times of 20% flusilazole suspension concentrate and 800 times of 50% carbendazim suspension concentrate are used, the control effects are 92.25% and 87.33% respectively.

[0037] The above-mentioned dispersant is one of sodium alkylnaphthalene sulfonate or sodium lignin sulfonate; the wetting agent is one of sodium lauryl sulfate and pull-off powder; the preservative is A kind of in sodium benzoate, citric acid; Described antifreezing agent is a kind of in ethylene glycol, glycerin; Described ...

Abstract

The invention belongs to the pesticide field and in particular relates to a bactericide for treating pear scab. The technical scheme is as follows: the bactericide comprises the following active ingredients: 5-80% of flusilazole and 8-80% of carbendazim by mass fraction. The bactericide compounded by flusilazole and carbendazim is efficient, low-toxic and systemic, has broad spectrum and has better control effect on various diseases of the fruit trees, vegetables and wheat, such as scab, brown spot, powdery mildew, anthracnose, smut, ring rot, anthracnose, leaf mould, fusarium head blight, etc.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a fungicide for treating pear scab. Background technique [0002] At present, pear scab spreads all over the pear producing areas. It is the main disease of pear trees, seriously affects the quality of pears, and has a tendency to develop and spread in recent years. The single-preparation plant fungicide has a single effect and the bacteria are prone to resistance. In order to improve the control effect and delay the emergence of bacterial resistance, our company has developed two active ingredients composed of flusilazole and carbendazim with different mechanisms of action. Phytobicides, [0003] Therefore, research and development a kind of cost is lower, can effectively treat pear scab, and the pesticide preparation of low toxicity becomes the development trend. Contents of the invention [0004] The purpose of the present invention is to overcome the existing defects and provide...
