example 1

[0041] Bioassay Example 1: Toxicity determination of trifloxystrobin and pyricloxazole complex against downy mildew

[0042] Test object: Tomato downy mildew

[0043] Test method: refer to the indoor bioassay test guidelines for fungicides and pesticides "The People's Republic of China Agricultural Industry Standard NY / T 1156.6-2006" and the creation of the SOP for the evaluation of biological activity of pesticides (fungicide volume), using the spore suspension spray inoculation method. Select potted tomato seedlings with the same growth at the 1 leaf and 1 heart stage (remove the growth point), and dry them naturally after spraying the medicament. After 24 hours, use a brush to dip in distilled water to wash off the sporangia on the back of the diseased leaves, and make a sporangia suspension (2 -3×10 5 Individual / ml), the sporangium suspension is evenly sprayed on the cucumber leaf with an inoculation sprayer (pressure 0.1MPa), then the tomato seedlings are moved to the ar...

Embodiment 1

[0057] Example 1: 61% trifloxystrobin·pyridoxazole wettable powder

[0058]

[0059] The active ingredient, various auxiliary agents, etc. are fully mixed according to the ratio of the formula, and after being pulverized by an ultrafine pulverizer, a 61% trifloxystrobin-pyridoxazole wettable powder can be obtained.

[0060] Pyridoxazole in this embodiment can be replaced by fluconazole, silfluconazole, and tetrafluconazole to form a new embodiment.

[0061] The 61% trifloxystrobin-pyridoxazole wettable powder prepared in this example was applied to control tomato downy mildew. The 61% trifloxystrobin-pyridoxazole wettable powder was diluted 5000 times with water and sprayed, and the control effects were 82.5%, 92.3% and 89.7% 1 day, 7 days and 15 days after the application. 25% trifloxystrobin suspension was used at 3500 times and 25% pyridoxazole emulsifiable concentrate was used at 5000 times by the same method, and the imitation was 75.6% and 80.7% respectively at 1 day...

Embodiment 2

[0062] Example 2: 50% Trifloxystrobin Pyridoxazole Suspension Concentrate

[0063]

[0064] Mix the active ingredient, dispersant, wetting agent, antifreeze agent, thickener, defoamer and water according to the proportion of the formula, and grind it with a sand mill to obtain 50% trifloxystrobin · pyriclostrobin Azole suspension.

[0065] Pyridoxazole in this embodiment can be replaced by fluconazole, silfluconazole, and tetrafluconazole to form a new embodiment.

[0066] The 50% trifloxystrobin-pyridoxazole suspension concentrate prepared in this example is applied to the prevention and treatment of wheat rust. 50% trifloxystrobin·pyridoxazole suspension was diluted 6000 times with water and sprayed, and the control effects were 97.6% and 95.3% 7 days and 15 days after the application. 25% Trifloxystrobin Suspension Concentrate was used by 3500 times and 25% Pyridoxazole EC by 5000 times, and used in the same way, the control effects were 89.5%, 82.9% and 90.4%, respect...

Abstract

The invention discloses a compound pesticide sterilization composition containing trifloxystrobin. Effective ingredients comprise the trifloxystrobin and an ingredient B, wherein the ingredient B is one kind of materials from SYP-Z048, triflumizole, simeconazole or tetraconazole, the weight ratio of the simeconazole to the ingredient B is 60:1-1:60. The trifloxystrobin in the composition provided by the invention has the obvious synergistic effect after being compounded with one kind of the materials from SYP-Z048, triflumizole, simeconazole or tetraconazole, the compound pesticide sterilization composition is used for the disease control of crops such as fruit trees, wheat, rice, and vegetables and is particularly suitable for the control on various diseases such as downy mildew diseases, rust diseases, powdery mildew diseases, leaf spot diseases, scab diseases, and rice blast diseases.

Description

Technical field [0001] The present invention relates to a bactericidal pesticide composition, in particular to a pesticide bactericidal composition compounded with trifloxystrobin and one of the azoles tricloxiconazole, trifluconazole, siloflurazole and tetrafluoroethazole. Background technique [0002] In recent years, due to single-use and unscientific use of drugs, many diseases have become resistant to currently used pesticides, such as downy mildew, powdery mildew, rice blast, etc., which has become a major problem in chemical control. At the same time, frequent pesticide application increases the burden on farmers and intensifies environmental pollution. Therefore, there is an urgent need for new varieties of fungicides that are efficient, low-potency, environmentally friendly, and low-residue. [0003] Trifloxystrobin broad-spectrum fungicides are a new class of fluorinated fungicides successfully developed from the natural product Strobilurins as lead fungicide comp...
