Embodiment 1

[0016] Embodiment 1 (51% spirodiclofen·profenofos emulsifiable concentrate):

[0017] Spirodiclofen 1%, profenofos 50%, N-methylpyrrolidone 10%, Nongru 500#5%, Nongru600#5%, acetic acid amount, xylene supplemented to 100%.

[0018] Add the active ingredient, emulsifier and auxiliary agent into the mixing kettle in sequence according to the proportion of the formula, and stir evenly to obtain 51% spirodiclofen·profenofos emulsifiable concentrate.

[0019] Profenofos in this example can be replaced by chlorpyrifos or methidon to form a new example.

Embodiment 2

[0020] Embodiment 2 (35% spirodiclofen profenofos emulsion in water):

[0021] 5% of spirodiclofen, 30% of profenofos, 10% of N-methylpyrrolidone, 5% of calcium dodecylbenzenesulfonate, 5% of Nongru 600#, appropriate amount of acetic acid, and deionized water to make up to 100%.

[0022] Add the original drug, solvent, and emulsifier together to dissolve into a uniform oil phase; mix the water-soluble components with water to make a water phase; mix the oil phase with the water phase under high-speed stirring to make a water emulsion.

[0023] Profenofos in this example can be replaced by chlorpyrifos or methidon to form a new example.

Embodiment 3

[0024] Embodiment 3 (24% spirodiclofen profenofos microemulsion):

[0025] Spirodiclofen 6%, profenofos 18%, N-methylpyrrolidone 10%, calcium dodecylbenzenesulfonate 8%, Nongru 600#7%, Nongru 1601#5%, acetic acid amount, deionized Water topped up to 100%.

[0026] Add the original drug, solvent, and emulsifier together to dissolve into a uniform oil phase, slowly add to water under stirring, then rapidly invert the phase after stirring and heating, and cool to room temperature to prepare a microemulsion.

[0027] Profenofos in this example can be replaced by chlorpyrifos or methidon to form a new example.

Abstract

The invention relates to a pest-killing and mite-killing composition containing tetronic acid and organophosphorus, wherein active ingredients of the pest-killing and mite-killing composition are spirodiclofen and any of organophosphorus pesticides such as profenofos, chlorpyrifos and methidathion, the mass portion ratio of the spirodiclofen to the organophosphorus pesticide is between 5 to 1 and 1 to 50, and the preferable ratio is between 2 to 1 and 1 to 19. The mixing of the spirodiclofen and the profenofos or the chlorpyrifos or the methidathion has apparent synergistic effect on pest mites, has good quick action and long lasting period, has control function on pests at the same time, is helpful to delay the drug resistance of the pest mites, and is mainly used for mite pest control of crops such as fruit trees, cotton, vegetables and so on.

Description

technical field [0001] The invention relates to an insecticidal and acaricidal composition, in particular to a synergistic insecticidal and acaricidal composition containing spirodiclofen and organic phosphorus insecticide active ingredients. Background technique [0002] Acarid pests, commonly known as red spiders, have many generations and strong reproductive ability. Under suitable temperature and humidity conditions, the number of mites can multiply rapidly in a short period of time, and the generations alternate, and are prone to resistance to acaricides. It is one of the most important pest species on fruit trees, vegetables and other crops. Due to the frequent occurrence of harmful mites and the frequent use of pesticides, pest mites have developed varying degrees of resistance to most of the acaricides used, and the control effect is not ideal. At the same time, frequent application of pesticides has increased the burden on farmers and increased environmental polluti...
