Embodiment 1

[0026] Example 1: 24% pyraclofen-fluazinam suspension concentrate

[0027] The contents of the following substances are all percentages by weight: 12% pyraclofen, 12% fluazinam, 8% alkyl polyoxyethylene ether sulfonate, 6% sodium dodecylbenzenesulfonate, xanthan gum 1%, isothiazolinone 0.2%, silicone compound 0.2%, ethylene glycol 2.5%, and deionized water to make up to 100%. The above-mentioned materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sand-milled in a sand mill to prepare 24% pyraclofen-fluazinam suspension concentrate.

[0028] The above-mentioned 24% pyraclofen-fluazinam suspension is used to prevent and control apple spider mites: 24% pyrazafen-fluazinam suspension is applied at 80 mg a.i. / kg, and the effect on apple spider mites is 7 days and 14 days after the drug. The control effects were 93.62% and 86.59% respectively; 12% fenpyrafen suspension was applied at 80 mga.i. / kg, and the control effects on apple red spiders were 81.4...

Embodiment 2

[0029] Example 2: 60% pyraclofen-fluazinam water dispersible granules

[0030] The contents of the following substances are all percentages by weight: 15% pyraclofen, 45% fluazinam, 8% polyoxyethylene-polyoxypropylene block copolymer, 6% sodium alkyl succinate sulfonate , sodium carboxymethyl starch 5%, white carbon black 5%, kaolin to make up to 100%. The above-mentioned materials are mixed in proportion, and after being uniformly mixed by airflow milling, kneading and granulating, drying and sieving, the 60% pyraclofen-fluazinam water-dispersible granule can be prepared.

[0031] Use the above-mentioned 60% pyrazafen-fluazinam water-dispersible granules to prevent and control eggplant cinnabarinus: 60% pyrenzafen-fluazinam water-dispersible granules are applied at 50 g a.i. / ha, 7d, 14d after treatment The control effects against Tetranychus cinnabarinus on eggplant were 87.61% and 81.49% respectively; 15% pyraclofen water dispersible granules were applied at 50g a.i. / ha, an...

Embodiment 3

[0032] Example 3: Indoor Toxicity Determination Test of Cyclopyrafen and Fluazinam on Apple Spider Mite

[0033] Test method: Refer to "Indoor Bioassay Test Guidelines for Pesticides Insecticides NY / T1154.12-2008", and adopt spider mite glass slide dipping method.

[0034] Statistical analysis was carried out with DPS statistical analysis software, and the LC of each drug was calculated 50 , and calculate the co-toxicity coefficient (CTC value) of the mixture according to Sun Yunpei's method, the co-toxicity coefficient (CTC) ≥ 120 shows the synergistic effect; the co-toxicity coefficient (CTC) ≤ 80 shows the antagonism; CTC)<120 showed an additive effect.

[0035] Table 1 The results of the indoor toxicity test of the compound of pyraclofen and fluazinam on the apple spider mite

[0036] Drug name and proportion (weight ratio)

[0037]It can be seen from Table 1 that when the compounding of pyrazafen and fluazinam in the weight ratio range of 20:1 to 1:20, the co-...

Abstract

The invention discloses a pesticide composition containing cyenopyrafen and fluazinam. Effective active components include cyenopyrafen and fluazinam, and a weight ratio of cyenopyrafen to fluazinam is 30:1-1:30. The pesticide composition has excellent prevention and control effects on mite type injurious insects on crops such as fruits and vegetables and is long in efficacy lasting period and safe to crops. By compounding of cyenopyrafen and fluazinam, remarkable synergistic effects are achieved, pesticide consumption can be reduced, utilization cost is reduced, environmental pollution is abated, generation of drug resistance of the mite type injurious insects is retarded, and service lives of pesticides are prolonged.

Description

technical field [0001] The invention relates to a pesticide composition and its application field, in particular to a binary compound compounded with pyrazafen and fluazinam as effective active ingredients, and is mainly used for the prevention and control of acarid pests on crops. Background technique [0002] Cyenopyrafen: It belongs to a new type of pyrazole acaricide. The mechanism of action is that the agent is metabolized into a hydroxyl form and activated to produce activity. This hydroxyl form inhibits the mitochondria by disturbing the complex II in the respiratory electron transport chain. Efficiency, thereby hindering electron transfer and disrupting the oxidative phosphorylation process. It is mainly used to prevent and control various harmful mites on eggplant, pepper, cucumber, pear, strawberry, citrus and other fruits, vegetables, and tea. It has good quick-acting and long-lasting effects. [0003] Fluazinam (fluazinam): It is a new type of substituted anilin...
