Acaricidal composition containing spirodiclofen and cyflumetofen

Abstract

The invention relates to an acaricidal composition, in particular to an acaricidal composition containing spirodiclofen and cyflumetofen, which is particularly used for preventing panonychus citri, European red mites, European red two-spotted spider mites and cotton leaf mites. The acaricidal composition has an obvious synergistic effect on mite killing as compared with a single pesticide, can kill egg, larva, nymph and adult of acarid, and is contributed to postponing the generation of pesticide resistance of bacteria.

Description

Technical field

[0001] The present invention relates to the field of pesticides, in particular the present invention relates to an acaricidal composition, in particular, the present invention relates to an acaricidal composition containing spirofendidiclofen and cyflufenate.

Background technique

[0002] Spider mites are the main species that parasitize plants, and are important pests that harm fruit trees, vegetables, and flowers. Mites are small individuals, widely distributed, and highly adaptable; they reproduce rapidly, have a short life cycle, and their wintering sites vary greatly; their population structure is complex, and mites of all growth stages can exist in a group, including eggs, nymphs, and juveniles and adult mites, etc.; it has strong adaptability to adverse environments and is easy to develop resistance to chemicals. All of these determine that the control of mites is more difficult.

Embodiment 1

[0045] Embodiment 1 (30% emulsifiable concentrate, active ingredient ratio 2:1)

[0046] Spirodiclofen 20%, Cyflumetate 10%, Nongru 2201 # 7.5%, agricultural milk 600 # 4.5%, DMF 8%, mineral spirits 150 to make up to 100%.

Embodiment 2

[0047] Embodiment 2 (25% emulsifiable concentrate, active ingredient ratio 4:1)

[0048] Spirodiclofen 20%, Cyflufenid 5%, Nongru 500 # 5%, Nongru 0201B 10%, dimethylformamide 12%, mineral spirits 150 to make up to 100%.

Embodiment 3

[0049] Embodiment 3 (42% emulsifiable concentrate, active ingredient ratio 20:1)

[0050] 40% of spirodiclofen, 2% of cyflufen, 6% of Nongru 0203B, 9% of Nongru 0201B, 8% of cyclohexanone, and 150 solvent naphtha to make up to 100%.

[0051] 2. Preparation of wettable powder

[0052] The general preparation method is as follows: fully mix the original drug, various additives and fillers according to the formula requirements, and pulverize through an ultra-fine pulverizer to obtain the processed product.
