Embodiment 1

[0021] Embodiment 1: the insecticidal composition is a suspending agent, and the percentages of each component are respectively:

[0022]

[0023]

[0024] The specific operation steps are: first mix other additives, shear and mix evenly in a shearing machine, then add active ingredients A and B, and grind in a ball mill for 2-3 hours, so that the particle diameters are all below 5 μm. Prepare the suspension formulation of the insecticidal composition of the present invention.

Embodiment 2

[0025] Embodiment 2: the insecticidal composition is an emulsion in water, and the percentages of each component are respectively:

[0026]

[0027] The specific operation steps are as follows: the active ingredients A and B, a solvent and an emulsifier are mixed together to dissolve into a uniform oil phase. Then mix some water and other additives together to dissolve into a uniform water phase. Then add the oil phase to the water phase while stirring at high speed in the reactor, slowly add water until reaching the phase inversion point, then perform high-speed shearing, and add the remaining water, and shear for about 30 minutes to obtain the insecticidal combination of the present invention water emulsion formulations.

Embodiment 3

[0028] Embodiment 3: the insecticidal composition is a microemulsion, and the percentages of each component are respectively:

[0029]

[0030]

[0031] The specific operation steps are: completely dissolve the active ingredients A and B with a solvent and a co-solvent, then add other adjuvants, mix well, finally add water, and after fully stirring, the microemulsion preparation of the insecticidal composition of the present invention can be obtained .

Abstract

The invention discloses a flonicamid-Paichongding insecticidal composition. The flonicamid-Paichongding insecticidal composition comprises flonicamid as a first effective component, Paichongding as a second effective component, and common assistant components. A weight ratio of flonicamid to Paichongding in the insecticidal composition is in a range of 20: 1 to 1: 20. A lot of indoor and outdoor experiments prove that the flonicamid-Paichongding insecticidal composition can produce obvious synergism, has good effects of preventing and controlling injurious insects such as aphid and plant hopper, reduces an insecticide use amount, insecticide residues on crops and environmental pollution, and delays production of insecticide resistance of injurious insects.

Description

technical field [0001] The invention relates to a pesticide insecticidal composition and its application field, in particular to an insecticidal composition with flonicamid and pichamid as active ingredients. Background technique [0002] Flunicamid is a new type of low-toxicity pyridinamide insecticide with contact and stomach toxicity. Aphids and other piercing-sucking mouthparts will be quickly prevented from sucking the juice after inhaling the plant juice with flonicamid, and there will be no excrement at all within 1 hour, and eventually die due to starvation, and the drug effect is slow. It can penetrate from roots to stems and leaves, but the penetration from leaves to stems and roots is relatively weak. It is extremely safe for people, animals and the environment. [0003] Pichamid is a new type of neonicotinoid insecticide with high efficiency, low toxicity and broad spectrum. It is mainly used to control Homoptera pests and has a good control effect on rice plan...
