Example Embodiment
[0028] Formulation Example 5: 60% pyridin-ethyl-etoxazole water dispersible granules.
[0029] Nitrofen 40%, etoxazole 20%, alkylphenol polyoxyethylene ether 10%, sodium dodecylbenzene sulfonate 10%, sodium carbonate 3%, polyvinyl alcohol 2%, and kaolin make up 100%. Mix the above active ingredients, dispersant, wetting agent, disintegrant, binder and filler uniformly, pulverize with an ultrafine jet mill, knead, and then add to a fluidized bed granulation dryer for granulation, drying, After sieving, 60% pyridin·etoconazole water dispersible granules can be prepared.
[0030] Formulation Example 6: 20% pyridin-ethyl oxazole ultra-low volume liquid.
[0031] Nitrofen 15%, etoxazole 5%, N-methylpyrrolidone 10%, N,N-dimethylformamide 15%, calcium dodecylbenzenesulfonate 2%, castor oil polyoxyethylene ether 2%, double kill 1.5%, second-line oil make up to 100%. After stirring and dissolving the above-mentioned active ingredients in a solvent, adding other auxiliary agents, fully stir...
Example Embodiment
[0032] Formulation Example 7: 10% fenpyramate·etoxazole microcapsule suspension
[0033] Pyramid 7%, etoxazole 3%, aliphatic polyamide resin 8%, corn methyl ester oil 10%, polyoxyethylene lauryl ether 10%, sodium hydroxide 2%, polycarboxylate 3%, to Ionized water makes up to 100%. Mix the above-mentioned active ingredients, polymer capsule wall materials, and solvents to dissolve into a uniform oil phase. Under shear conditions, add the oil phase to the aqueous solution containing emulsifiers, pH regulators, and dispersants. Fill up with deionized water, the two materials react at the oil-water interface to form a polymer capsule wall, and then a 10% pyridin-ethyloxazole microcapsule suspension can be prepared.
[0034] Formulation Example 8: 15% pyridanfen·etoxazole hot spray.
[0035] Tetrafenpyran 10%, etoxazole 5%, cyclohexanone 5%, N-methylpyrrolidone 10%, alkylphenol polyoxyethylene ether 10%, sodium lauryl sulfate 5%, azone 2% , Triphenyl phosphate 1%, vegetable oil to make...
Example Embodiment
[0036] Bioassay Example 1: Indoor combined virulence determination of fenpyramate and etoxazole on red spider citrus.
[0037] Test insects: select citrus red spider nymphs collected in the field and raised indoors.
[0038] Test agents: 96% pyridin-methyl and 93% etoxazole.
[0039] The test method adopts the leaf butterfly spray method, and the specific operation method is as follows:
[0040] Choose healthy citrus leaves and use a puncher to make leaf butterflies. Place a wet sponge block in the petri dish, place filter paper on it, and place leaf butterflies on the filter paper. Put 2 leaf butterflies in each dish. Choose healthy and old The nymphs of the citrus red spider mites are inoculated on the leaf butterflies, 20 per leaf butterfly.
[0041] Place the petri dish with leaf butterfly under the potter spray tower, spray at 50PSI pressure, the spray volume is 1ml, take out the petri dish after 1 min of sedimentation, and then put the treated petri dish in the 25℃, 12H / 12H light...
