Embodiment 1 3

[0018] Embodiment 1 Tricyclazole and epoxiconazole are compounded to the determination of the efficacy of rice blast seedling blast

[0019] Test object: Pyricularia grisea

[0020] Test method: refer to the NYT 1156.8-2007 Pesticide Indoor Bioassay Test Guidelines of the People's Republic of China. The test crops are rice blast-susceptible varieties. After germination, 20 seeds are sown in each pot, and 10 rice plants with 3 leaves and 1 heart stage with the same growth are selected for future use. On the basis of the preliminary test, set 5-7 series of mass concentrations according to the activity of the drug. Spray the medicinal liquid evenly on the leaf surface until it is completely wet, preferably without dripping water, and wait for the medicinal liquid to dry naturally for later use. Each pot was treated with 4 repetitions, and the treatment containing only solvent and surfactant but no active ingredient was set as a blank control. After 24 hours of chemical treatme...

Embodiment 2 3

[0040] Example 2 Indoor efficacy determination of tricyclazole and epoxiconazole compounded against rice sheath blight

[0041] Test object: rice sheath blight (Rhizoctonia solani)

[0042] Test method: refer to the NYT 1156.5-2006 Pesticide Indoor Bioassay Test Guidelines of the People's Republic of China. Select broad bean susceptible varieties for potting, cut leaves with petioles in the same part of the same growth, put them in a petri dish, and keep them moist for later use. On the basis of the preliminary test, set 5-7 series of mass concentrations according to the activity of the drug. Fully infiltrate the leaves in the pre-prepared medicinal solution for 5 seconds, drain off the excess medicinal solution, air-dry naturally, and then moisten and cultivate according to the treatment label. Spray evenly on the leaf surface until it is completely wet, preferably without dripping water, and wait for the liquid to dry naturally for later use. Each treatment of 30 leaves w...

Embodiment 351

[0049] Embodiment 351% (wt%, hereinafter the same) tricyclazole econazole wettable powder

[0050] Composition: Tricyclazole 50%, Cycloconazole 1%, Sodium Lauryl Sulfate 2%, Sodium Lignosulfonate 5%, Naphthalene Sulfonate 3%, Kaolin Clay to 100%.

[0051] Preparation: The ingredients are fully mixed, and pulverized by a superfine pulverizer in a conventional manner to obtain a wettable powder.

[0052] Application in the prevention and control of rice seedling blast: the test was carried out according to the guidelines for field efficacy tests of pesticides of the People's Republic of China GBT17980.19-2000. The dosage of 51% tricyclazole · econazole wettable powder formulated according to the above ratio has a control effect of 85.3% on rice seedling blast when the dosage is 300 g / ha, which is obviously better than that of a single agent, and the dosage of active ingredients is lower than that of each Single dose. The test results are shown in Table 3.

Abstract

The invention discloses a bactericidal pesticide composition. The composition consists of tricyclazole and epoxiconazole which serve as active medicinal ingredients and acceptable auxiliary ingredients in a pesticide, wherein the weight ratio of the tricyclazole to the epoxiconazole is 1:50-60:1. A test indicates that the combination of the two active medicinal ingredients can obtain remarkable cooperative and synergistic action, can effectively prevent and control rice blast at every stage of paddy rice, has good prevention and control effects on diseases such as banded sclerotial blight, false smut and the like at the later stage of paddy rice, contributes to delaying medicament resistance, reduces medicament dosage, lowers cost and expands the application range of a medicament.

Description

technical field [0001] The invention relates to a compounded bactericidal pesticide composition. Background technique [0002] Rice blast is one of the most important plant diseases in the world, caused by the blast fungus Pyricularia grisea. The pathogen can invade the host at any stage of the rice growth period, and the disease occurs in almost all rice cultivation areas. In the year when the disease is prevalent, the production is generally reduced by 10%-20%, and the heavy one can reach 40%-50%. In severe cases, even the grains will not be harvested. Neck blast is a kind of "rice blast" that occurs on the neck of the ear when rice is heading. After the ear neck is infected, white ears or shrunken grains will form at the panicle neck nodes. Once the ear neck is infected with rice blast, the yield will be severely reduced. Severe ones can also basically fail. Sheath blight is caused by the rice sheath blight bacterium Rhizoctonia solani. It mainly occurs from the tiller...
