Problems solved by technology

[0008] In the actual process of agricultural production, the application of chemical agents is the most effective means of controlling plant diseases and insect pests, but the most likely problem caused by chemical control of pests is the emergence of pest resistance
Moreover, long-term continuous high-dose application of a single chemical insecticide is likely to cause a series of problems such as drug residues and environmental pollution.

Embodiment 1

[0093] Embodiment 1: (40% dinotefuran · pyridaben aqueous suspension concentrate)

[0094] Components and content: dinotefuran, 10%; pyridaben, 30%; emulsifier Nongru NP-10, 1%; dispersant polycarboxylate, 3%; thickeners choose xanthan gum and silicic acid Magnesium aluminum, the dosage is 0.05% and 1% respectively; antifreeze agent ethylene glycol, 3%; antifoaming agent silicone compound, 0.2%; water, balance.

[0095] The preparation method of the above example 1 is as follows: according to the components and weight percentages provided in the examples, dinotefuran, pyridaben, surfactants and other functional additives are placed in the reaction kettle in sequence, and water is added to mix evenly. After high-speed shearing, wet sanding, and finally homogeneous filtration, the water-suspending agent can be obtained. The main equipment is batching kettle, colloid mill or homogeneous mixer, sand mill.

Embodiment 2

[0096] Embodiment 2: (35% dinotefuran · pyridaben water dispersible granule)

[0097] Components and content: dinotefuran, 10%; pyridaben, 25%; wetting agent sodium lauryl sulfate, 4%; dispersant, alkylnaphthalene sulfonate formaldehyde condensate, 7%; disintegrant Ammonium sulfate, 20%; filler attapulgite, balance.

[0098] The preparation method of the above-mentioned Example 2 is: according to the components and their weight percentages provided in the examples, dinotefuran, pyridaben, dispersant, wetting agent and filler are mixed evenly, and after being pulverized by a jet mill, add 10- 25% water, then kneading, extrusion granulation, and drying to obtain water-dispersible granules. Or spray the pulverized powder with water in a boiling granulator, granulate, dry, and then sieve to obtain water-dispersible granules. The main equipments are mixer, jet mill, kneader, extrusion granulator, drying room or fluidized bed drying, or boiling granulator, screening machine.

Embodiment 3

[0099] Embodiment 3: (18% dinotefuran · pyridaben aqueous emulsion)

[0100] Components and content: dinotefuran, 4%; pyridaben, 14%; emulsifier Nongru BY-125, 3%; emulsifier nonylphenol polyoxyethylene ether phosphate 3%; solvent selection cyclohexanone and Xylene, consumption is 8% and 20% respectively, antifreeze is selected propylene glycol, consumption 4%, water, balance.

[0101] The preparation method of the above-mentioned Example 3 is: according to the components and weight percentages provided in the examples, add dinotefuran, pyridaben, emulsifier, and solvent into the mixing tank, stir until completely dissolved, and set aside; add propylene glycol and Add water into the shearing kettle, turn on the shearing equipment, slowly add the dissolved dinotefuran pyridaben solution into the shearing kettle dropwise, and continue shearing for half an hour after the dropping to obtain the aqueous emulsion. The main equipment is mixing kettle and shearing kettle.

Abstract

The invention belongs to the technical field of agricultural insecticides and particularly relates to a pesticide composition for preventing and treating striped flea beetles. The pesticide composition comprises the effective components of dinotefuran and pyridaben. The composition further comprises a surfactant and/or other functional axillaries and can be prepared into dosage forms such as a suspending agent, wettable powder, a water dispersible granule, emulsion in water, missible oil and the like, wherein the effective components consisting of dinotefuran and pyridaben account for 10-80% of the total weight. The composition is low in toxicity and high in efficiency, and the insecticidal spectrum is expanded. The composition particularly has excellent insecticidal activity on striped flea beetles. Generation of resistance to drugs is delayed, the lasting period is prolonged and the environmental pollution is reduced while the dosage is reduced, and the composition is safe and free of pesticide hazard to plants.

Description

technical field [0001] The invention belongs to the technical field of agricultural insecticides, in particular to a pesticide composition for preventing and controlling flea beetle. Background technique [0002] Dinotefuran is a neonicotinoid insecticide developed by Mitsui Corporation of Japan. Its chemical structure is very different from that of the existing neonicotinoid insecticides. Its tetrahydrofuryl group replaces the previous chloropyridyl and chlorothiazolyl groups, and it does not contain halogen elements. At the same time, it is also different from nicotine in terms of performance, so people call it "furan nicotine" at present. The agent has the characteristics of contact killing, stomach toxicity and root systemic absorption, high quick-acting effect, long-lasting effect of 3 to 4 weeks (theoretical lasting effect is 43 days), wide insecticidal spectrum, etc., and has excellent protection against piercing and sucking mouthparts pests. Effectiveness and high ...
