Examples
Embodiment 1
[0051] Embodiment 1: 5% tofenpyram·beta-cypermethrin microemulsion
[0052] 98% Fenpyrad 2.55g
[0053]95% beta-cypermethrin technical 2.63g
[0054] Dimethylformamide (solvent) 10g
[0055] Tristyrylphenol polyoxyethylene polyoxypropylene ether (emulsifier) 5g
[0056] Calcium dodecylbenzenesulfonate (emulsifier) 5g
[0057] Water to make up to 100g.
[0058] The original drug, solvent and emulsifier are added together to dissolve into a uniform oil phase; under high-speed stirring, the oil phase is mixed with water to prepare a 5% pyrethrin-beta-cypermethrin microemulsion.
[0059] The compound agent of this example is applied to prevent and control cabbage pests (Plutella xylostella and aphids), and the dosage and control effect after 3 days are shown in Table 3. It can be seen from Table 3 that the amount of pyrenpyramid used in the field is relatively large, and the control effect on diamondback moth and aphids is not much different, between 80% and 85%, while th...
Embodiment 2
[0063] Example 2: 24% Fenpyramid · Beta-cypermethrin EC
[0064] 98% Fenpyran 20.41g
[0065] 95% beta-cypermethrin technical 4.21g
[0066] Calcium dodecylbenzenesulfonate (emulsifier) 5g
[0067] Tristyrylphenol polyoxyethylene polyoxypropylene ether (emulsifier) 5g
[0068] Xylene (solvent) was made up to 100 g.
[0069] Add the active ingredient, emulsifier and solubilizing agent into the mixing kettle according to the formula, and stir evenly to prepare 24% tonamiprole·beta-cypermethrin emulsifiable concentrate.
[0070] The compound agent of this example is applied to control cucumber pests (whitefly and Liriomyza sativae), and the control effect after 3 days of treatment is shown in Table 4. It can be seen from Table 4 that the control effect of tolfenpyrad against Liriomyza sativae is poor, that of beta-cypermethrin against whitefly is poor, and that the compound has good control effects on both kinds of pests.
[0071] Table 4, the test results of the compoun...
Embodiment 3
[0073] Embodiment 3: 22% Fenpyradradeltamethrin suspension concentrate
[0074] 98% Fenpyran 2.04g
[0075] 98.5% deltamethrin technical 20.30g
[0076] Sodium methylnaphthalenesulfonate formaldehyde condensate (wetting and dispersing agent) 5 grams
[0077] Xanthan gum (thickener) 1 g
[0078] Bentonite (thickener) 1g
[0079] Glycerin (antifreeze) 4 grams
[0080] Water to make up to 100g.
[0081] Active components, dispersant, wetting agent, water and other components are uniformly mixed according to the ratio of the formula, and ground to obtain a 22% Fenpyramid·Deltamethrin suspension concentrate.
[0082] The compound agent of this example is applied to prevent and control jujube pests (slug moths, Lygus aureus), and the control effect 1 day after the medicine is shown in Table 5. It can be seen from Table 5 that the control effect of the compound agent on jujube pests 1 day after the application is significantly higher than that of the two control agents, both re...
