Embodiment 1

[0071] Example 1: Indoor virulence determination of Sclerotium rolfsii Sacc. aligned with cyprodinil and prochloraz. The test object was collected from the field (Zhengyang County, Henan Province). Sclerotium rolfsii Sacc.

[0072] Table 1. Indoor virulence test results of Sclerotium rolfsii Sacc. aligned with cyprodinil and prochloraz.

[0073]

[0074] It can be seen from Table 1 that the mixture of cyprodinil and prochloraz at a ratio of 50:1 to 1:50 has obvious synergistic effects on Sclerotium rolfsii Sacc., and the co-toxicity coefficients are all 120 above; the mixture of cyprodinil and prochloraz at 40:1~1:40 has obvious synergistic effect on Sclerotium rolfsii Sacc., and the co-toxicity coefficients are above 130; The mixture of cyclamine and prochloraz between 30:1 and 1:30 has obvious synergistic effect on Sclerotium rolfsii Sacc., and the co-toxicity coefficients are all above 140; The mixture of fresh amine between 15:1 and 1:15 has obvious synergistic effect...

Embodiment 2

[0085] Example 2: 40% prochloraz · cyprodinil water dispersible granules

[0086] Weigh 20% prochloraz, 20% cyprodinil, 10% sodium lignosulfonate, 5% chitosan, 2% tea dry powder, 3% sodium bicarbonate, and the balance white carbon black. The above raw materials are uniformly mixed in a mixing tank, extruded, granulated, dried, and sieved to obtain 20% prochloraz·20% cyprodinil water-dispersible granules, using the same process and additive content (All the other auxiliary agents are of the same type, only the filler silica content is different) 20% prochloraz water-dispersible granules, 20% cyprodinil water-dispersible granules, 5% salicylic acid water-dispersible granules, 20% salicylic acid water-dispersible granules were prepared. % salicylic acid water dispersible granules, 20% cyprodinil 20% prochloraz 5% salicylic acid water dispersible granules, 20% cyprodinil 20% prochloraz 20% salicylic acid water dispersible granules .

[0087] Table 2 is used for the prevention an...

Embodiment 3

[0098] Example 3: 80% prochloraz · cyprodinil wettable powder

[0099] Weigh 40% cyprodinil, 40% prochloraz, 10% sodium lauryl sulfate, 2% glucose, 2% sodium polycarboxylate, 4% chitosan, and the rest kaolin. The active ingredient is mixed with other additives, mechanically pulverized and then jet-pulverized, and mixed uniformly to prepare 80% prochloraz·cyprodinil wettable powder.

Abstract

The invention discloses a sterilization composition containing cyprodinil and prochloraz, the effective constituents are the cyprodinil and the prochloraz, and the weight ratio of the cyprodinil and the prochloraz in the composition is (50:1)-(1:50); the total weight of the cyprodinil and the prochloraz accounts for 0.1%-0.8% of the weight of the composition, and the balance is auxiliaries; afterthe cyprodinil and the prochloraz are compounded at certain proportion, the synergism can be provided for indoor activity of the Sclerotium rolfsii Sacc., and the sterilization composition is suitablefor preventing and curing the peanut southern blight caused by the Selerotium rolfsii Sacc. and can also be suitable for preventing and curing other crop diseases such as peanut cercospora brown spotdisease, potato tarspot and rice sheath blight disease.

Description

Technical field [0001] The invention belongs to the field of pesticide compositions, and specifically relates to a bactericidal composition containing cyprodinil and prochloraz. Background technique [0002] Cyprodinil is a methionine biosynthesis inhibitor and a pyrimidinamine fungicide. Its chemical name is 4-cyclopropyl-6-methyl-N-phenylpyrimidin-2-amine, which is the same as triazoles and Imidazole, morpholine, phenylpyrrole, etc. have no cross-resistance and have protective, therapeutic, leaf penetration and root systemic activities. Foliar spray or seed treatment can also be used as a barley seed coating agent. It is mainly used to prevent and control crop diseases such as gray mold, sclerotinia, powdery mildew, scab, and leaf spot. [0003] Prochloraz is a broad-spectrum fungicide with apical conduction activity. Its mechanism of action is to inhibit the biosynthesis of ergosterol, thereby damaging the bacterial cell membrane function. It is effective for a variety o...
