Embodiment 1

[0059] Example 1: 22% pyridalyl chlorpyrifos water dispersible granules

[0060] 95% pyridalyl technical 2.11g

[0061] 95% chlorpyrifos technical 21.05g

[0062] Sodium lauryl sulfate (wetting agent) 2 g

[0063] White carbon black (adsorbent) 10 grams

[0064] Sodium lignosulfonate (dispersant) 5 g

[0065] Naphthalenesulfonate (dispersant) 3g

[0066] Kaolin (carrier) made up to 100 grams.

[0067] Use white carbon black to absorb pyridalipr, then fully mix it with chlorpyrifos technical material, various auxiliaries and fillers according to the formula, and pulverize it with an ultra-fine pulverizer to obtain 22% pyridalipal·chlorpyrifos water Dispersible granules.

[0068] In a paddy field (paddy rice is in the booting stage) that hardly has any management in Lingshui County, Hainan, this embodiment is applied to the prevention and treatment of rice leaf rollers, armyworms, rice planthoppers, and the results in 3 days after the medicine are shown in Table 4 . It c...

Embodiment 2

[0071] Embodiment 2: 21% pyridalyl-chlorpyrifos emulsion in water

[0072] 95% Pyridalyl Technical 1.05g

[0073] 95% chlorpyrifos technical 20.15g

[0074] Xylene (solvent) 10 grams

[0075] Tristyrylphenol ethoxylate phosphate (emulsifier) ​​4 g

[0076] Propylene glycol (antifreeze) 4 grams

[0077] Polydimethylsiloxane (defoamer) 0.3g

[0078] water to 100g

[0079] Add the original drug, solvent, and emulsifier together to dissolve into a uniform oil phase; mix water-soluble components (antifreeze, defoamer) and water to obtain a water phase; under high-speed stirring, mix the oil phase with water and mixed to prepare 21% pyridalyl-chlorpyrifos aqueous emulsion.

[0080] This embodiment is applied to the control of cotton bollworm and whitefly on cotton, and the dosage and control effect are shown in Table 5. As can be seen from Table 5: (1) the control effect of the compound agent on cotton bollworm is equivalent to that of pyridalyl, which has a better control ef...

Embodiment 3

[0083] Embodiment 3: 11% pyridalox-phoxim microemulsion

[0084] 95% Pyridalyl Technical 1.05g

[0085] 91% phoxim technical 10.99g

[0086] Dimethylformamide (solvent) 10g

[0087] Tristyrylphenol polyoxyethylene polyoxypropylene ether (emulsifier) ​​10g

[0088] Water to make up to 100g.

[0089] 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 11% acetamipro-chlorpyrifos microemulsion.

[0090] This embodiment is applied to control wheat pests. Midges occur lightly, and aphids occur heavily. The control effect of 3 days after the medicine is shown in Table 6. It can be seen from Table 6: because the occurrence of midge is relatively light, each treatment has better control effect on midge, and the control effect of the compound agent is the highest, reaching 95.1%; pyridalyl is very effective against wheat aphid under this dosage. Low, but the com...

Abstract

The invention relates to a pesticide combination, which is characterized by comprising the active ingredients including pyridalyl (A) and an organophosphorus insecticide (B) which can be chlorpyrifos, phoxim, profenofos, triazophos, diazinon, pyridaphenthione, malathion or acephate. The pesticide combination of the invention has good control effects on the common pests on such field crops as paddy rice, wheat, corns, cotton, hemp, soybean and the like, and especially has better control effect on lepidopterous pests.

Description

technical field [0001] The invention relates to a pesticide composition and application thereof, in particular to a pesticide composition containing pyridalyl. Background technique [0002] Organophosphorus insecticides are widely used in field crops due to their wide insecticidal spectrum, diversified insecticidal methods, and low cost. However, organophosphorus insecticides also have many problems, for example: the toxicity of many organophosphorus insecticides is relatively high; the dosage of most organophosphorus insecticides is large; Ma Enbo. Insect Resistance to Organophosphate Insecticides, "Chemistry of Life", 2003, 23(5)). Chlorpyrifos, phoxim, profenofos, triazophos, diazinon, pyridaphenthione, malathion, acetyl Methamidophos (acephate) has moderate or low toxicity and is an alternative to highly toxic organophosphate insecticides. At present, there are many compounding agents of organophosphorus insecticides, mainly including compounding between organophospho...
