Embodiment 1

[0036] A long-acting fungicide for crops, which is a suspending agent, which consists of: 1-90wt% of benthiamidazole, 1-10wt% of wetting agent, 1-10wt% of dispersant, 1-10wt% of stabilizer, antifreeze Agent 1-10 wt %, defoamer 1-10 wt %, and the balance is water. Its preparation method is:

[0037] Add the above composition into a stainless steel tank in proportion, use a high-speed shearing machine for mixing and primary crushing, and after 30 minutes, add the mixed solution to a horizontal sand mill for wet crushing, and continue grinding for 2 to 3 times to obtain the finished product sterilized agent.

Embodiment 2

[0039] A long-acting fungicide for crops, which is a soluble liquid and consists of 1-50 wt% of benzimazole, 10-80 wt% of glacial acetic acid, 1-10 wt% of emulsifier, and 1-10 wt% of synergist. Its preparation method is:

[0040] First add glacial acetic acid into a plastic mixing tank, then add benthiamidazole, and stir for 30 minutes to fully dissolve the benthiamidazole in glacial acetic acid, then add an emulsifier and a synergist, and stir to obtain a finished fungicide.

Embodiment 3

[0042] A long-acting fungicide for crops is a water-dispersible granule, which consists of 1-50 wt% of benthiamidazole, 1-10 wt% of a wetting agent, 1-10 wt% of a dispersing agent, and the balance is filler. Its preparation method is:

[0043] The various raw materials mentioned above are firstly processed into a suspending agent according to the formula, and then dried and granulated, or firstly processed into a wettable powder and then granulated to obtain a finished fungicide.

[0044] In above-mentioned implementation, used dispersant, stabilizing agent, antifreezing agent, defoamer, emulsifier, synergist, wetting agent and filler are the common adjuvant of pesticide field, and its specific selection does not affect technology of the present invention Disclosure of the program.

[0045] In addition to the above examples, the bactericide disclosed in the present invention can also be processed into aqueous emulsion, microemulsion, emulsifiable concentrate, wettable powder,...

Abstract

The invention relates to a long-acting bactericide for crops. The long-acting bactericide comprises a main agent and auxiliary agent, and the main agent contains fenbendazole. The animal pesticide fenbendazole is applied to the crop bactericide for the first time, and has a good effect. The long-acting bactericide disclosed in the invention has a better stability and a better rice blast control effect than the bactericide fenbendazole.

Description

technical field [0001] The invention relates to a long-acting fungicide for crops, belonging to the technical field of pesticide fungicides. Background technique [0002] In agricultural production, crop diseases caused by various pathogens will lead to obvious crop yield reduction, such as rice blast, sheath blight, and rice false smut. Its loss is huge, and there is an urgent need for a product that can prevent multiple diseases simultaneously. [0003] In the prior art, there is a crop fungicide Shi Baoling made of albendazole as an active ingredient. However, albimazole is firstly used as a kind of insecticide for humans and animals. It is not affected by natural conditions in humans and animals, so its efficacy is not affected. However, when albimazole is used as a pesticide, there is a stable The disadvantage of poor antibacterial properties is that its chemical structure is unstable to light and heat, and it will decompose in 3 to 5 days under natural conditions and...
