Embodiment 1

[0048] Embodiment 1:18% prothioconazole allyl isothiocyanate wettable powder (5:1)

[0049] Formula: 15% allyl isothiocyanate, 3% prothioconazole, 3% naphthalenesulfonic acid formaldehyde condensate sodium salt, 3% wetting and penetrating agent F, white carbon black to make up the balance;

[0050] Preparation method: mix the active ingredient, dispersant, wetting agent and filler uniformly, pulverize with a jet mill, and then perform secondary mixing to obtain the wettable powder of the present invention.

Embodiment 2

[0051] Embodiment 2: 15% prothioconazole allyl isothiocyanate wettable powder (2:1)

[0052] Formula: 10% allyl isothiocyanate, 5% prothioconazole, 6% sodium lignosulfonate, 4% sodium dodecylbenzenesulfonate, kaolin to make up the balance;

[0053] Preparation method: with embodiment 1.

Embodiment 3

[0054] Example 3: 30% prothioconazole allyl isothiocyanate water dispersible granules (1:2)

[0055] Formula: 10% allyl isothiocyanate, 20% prothioconazole, 6% fatty alcohol polyoxyethylene ether, 2% sodium dodecylbenzenesulfonate, 2% magnesium aluminum silicate, 0.5% carbonic acid Sodium hydrogen and white carbon black make up the balance;

Abstract

The invention relates to a bactericidal composition containing prothioconazole and allyl isothiocyanate, the composition comprises an active component A and an active component B, wherein the active component A is selected from prothioconazole, and the active component B is selected from allyl isothiocyanate. The weight ratio of the active component A to the active component B is 1:80-80:1, and the composition can be prepared into agriculturally allowable preparation forms, preferably wettable powder, water dispersible granules, suspending agents and micro-emulsions. The bactericidal composition can be used for preventing and treating diseases such as take-all disease, powdery mildew, gibberellic disease, gray mold, banded sclerotial blight, fusarium wilt, leaf spot, rust disease, sclerotinia sclerotiorum, brown rot, anthracnose, ring spot, early blight and scab, and has the characteristics of small dosage, rain wash resistance and obvious synergy.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a fungicidal composition containing prothioconazole and allyl isothiocyanate on crop diseases. [0002] technical background [0003] English name of prothioconazole: Prothioconazole, molecular formula: C 14 h 15 C l2 N 3 OS chemical name: (RS)-2-[2-(1-chlorocyclopropyl)-3-(2-chlorophenyl)-2-hydroxypropyl]-2,4-dihydro-1,2, 4-Triazole-3-thione. [0004] Prothioconazole is a new triadimefon systemic fungicide, as a demethylation inhibitor (DMI), it can inhibit the precursor of sterol in fungi - lanosterol at 14- or -24 Demethylation of methylene dihydrolanosterol. Through a large number of field efficacy tests, the results show that prothioconazole not only has good safety for crops, but also has a good effect on disease prevention and treatment, and has a significant increase in yield. Compared with triazole fungicides, prothioconazole has more Broad-spec...
