[0042] Bioassay Example 1: Toxicity determination of trifloxystrobin and pyricloxazole complex against downy mildew
[0043] Test object: Tomato downy mildew
[0044] Test method: Refer to the indoor bioassay test guidelines for fungicides and pesticides "The Agricultural Industry Standard of the People's Republic of China NY / T1156.6-2006" and the creation of SOPs 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 in 1 leaf and 1 heart stage (remove the growth point), and dry them naturally after spraying the medicine. After 24 hours, use a brush to dip distilled water to wash off the sporangia on the back of the diseased leaves, and make a sporangia suspension (2 -3×10 5 perml), spray the sporangia suspension evenly on the cucumber leaves with an inoculation sprayer (pressure 0.1MPa), and then move the inoculated tomato seedlings to an artificial ...
Embodiment 1
[0058] Example 1: 61% trifloxystrobin·pyridoxazole wettable powder
[0059]
[0060] The active ingredients and various auxiliary agents are fully mixed according to the proportion of the formula, and after being pulverized by an ultrafine pulverizer, 61% trifloxystrobin · pyridoxazole wettable powder can be obtained.
[0061] Pyridoxazole in this embodiment can be replaced by fluconazole, silfluconazole, and tetrafluconazole to form a new embodiment.
[0062] 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% on 1 day, 7 days, and 15 days after the application. 25% trifloxystrobin suspension concentrate was used at 3500 times and 25% pyridoxazole emulsifiable concentrate was used at 5000 times in the same way, and the imitation rates were 75.6% and 80....
Embodiment 2
[0063] Example 2: 50% Trifloxystrobin Pyridoxazole Suspension Concentrate
[0064]
[0065] 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.
[0066] Pyridoxazole in this embodiment can be replaced by fluconazole, silfluconazole, and tetrafluconazole to form a new embodiment.
[0067] The 50% trifloxystrobin-pyridoxazole suspension concentrate prepared in this example was applied to the prevention and treatment of wheat rust. Dilute 50% Trifloxystrobin Pyridoxazole Suspension Concentrate 6000 times with water and spray, and the control effect is 97.6% and 95.3% 7 days and 15 days after application. 25% trifloxystrobin suspensible concentrate was used by 3500 times and 25% pyridoxazole emulsifiable concentrate was used by 5000 times in the same way, and the control effects of 7 days a...
