Embodiment 3

[0017] Formulation Example 3: 60% benthiazil·fluazinam water dispersible granules.

[0018] Benthiopyram 3%, Fluazinam 57%, Sodium Lauryl Sulfate 6%, Dispersant Lignosulfonate (Sodium, Calcium) 4%, Disintegrant Sodium Chloride 2%, Binder Polymer Ethylene glycol 3%, stable soluble starch 3%, kaolin supplemented to 100%. The above formula is dry crushed, granulated, dried and sieved according to the proportion to prepare 60% benthiazin·fluazinam water dispersible granules.

Embodiment 4

[0019] Formulation Example 4: 50% benthiazil·fluazinam water dispersible granules.

[0020] Benthiopyram 2.5%, Fluazinam 47.5%, Sodium Lauryl Sulfate 6%, Dispersant Lignosulfonate (Sodium, Calcium) 4%, Disintegrant Sodium Chloride 2%, Binder Polymer Ethylene glycol 3%, stable soluble starch 3%, kaolin supplemented to 100%. The above formula is dry pulverized, granulated, dried and sieved according to the proportion to prepare 50% benthiazin·fluazinam water dispersible granules.

[0021] Formulation Example 5: 50% benthiazil·fluazinam wettable powder.

[0022] 2% benthiazil, 48% fluazinam, 3% pull-off powder, 6% lignosulfonate (sodium, calcium), 15% talcum powder, kaolin to make up to 100%. The above formula is coarsely pulverized in proportion, put into a mixer and mixed evenly, and then jet pulverized to obtain 50% benthiazin·fluazinam wettable powder.

[0023] Formulation Example 6: 40% benthiazil·fluazinam wettable powder.

Embodiment 1

[0025] Biological Assay Example 1: Indoor Toxicity Test of Phytophthora capsici by Mixing Benthiopyram and Fluazinam.

[0026] Table 1. Indoor toxicity test results for Phytophthora capsici.

[0027]

[0028] Calculate the toxicity index of each agent and the co-toxicity coefficient (CTC value) of the mixture according to Sun Yunpei's method. When CTC≤80, it is antagonism, 80﹤CTC﹤120 is additive, and CTC≥120 is synergistic.

[0029] It can be seen from Table 1 that the mixed mass ratio of benthiazil and fluazinam is 5:1 to 1:45, and the co-toxicity coefficients are all greater than 120, which has a synergistic effect on Phytophthora capsici.

Abstract

The invention relates to a benthiavalicarb isopropyl and fluazinam pesticide composition. The pesticide composition comprises a common auxiliary agent, benthiavalicarb isopropyl and fluazinam, wherein the mass ratio of the benthiavalicarb isopropyl to the fluazinam is 5:1-1:45, preferably 3:1-1:25. After the benthiavalicarb isopropyl is combined with the fluazinam, the synergistic effect is obvious, and the dosage of active ingredients of the compound chemicals is obviously less than that of the chemicals used alone. Therefore, the pesticide composition of benthiavalicarb isopropyl and fluazinam is applicable to controlling crop diseases caused by oomycota pathogens of chromista, and is particularly applicable to controlling late blight of potatoes, phytophthora blight of chilies and downy mildew of various crops.

Description

technical field [0001] The pesticide composition involved in the present invention uses benthiazil and fluazinam as active ingredients, and is suitable for preventing and treating crop diseases caused by pathogens of the oomycete of Pseudobacteria, especially potato late blight, pepper blight and various Crop downy mildew. Background technique [0002] Benthiazil, English common name benthiavalicarb-isopropyl; chemical name [[(6-fluorobenzothiazol-2-yl)-ethylcarbamoyl]-2-methylpropyl]carbamate isopropyl ester CAS login No. [177406-68-7], benthiazil has good fungicidal activity against Phytophthora, and it has a good inhibitory effect on the formation of sporangia and the germination of sporangia at low concentrations. Potato infestans resistant to benzamide functional groups and melon downy mildew resistant to methoxyacrylate functional groups had good fungicidal activity. [0003] Fluazinam, English common name fluazinam, chemical name 3-chloro-N-(3-chloro-5-trifluorometh...
