Embodiment 1

[0024] Weigh 3.16g95% pyrenpyrad technical, 15.79g95% nitenpyram technical, 4g1602 (dispersant), 1g2700 (dispersant), 1gNP-10 (wetting agent), 0.15g xanthan gum, 2g ethyl Glycol, 0.1g of silicone defoamer, 100g of water, after mixing, 10000r / min high-speed shearing for 2 minutes, added to a sand mill to grind to the required particle size (average particle size is less than 3 microns), made 18 % Fenpyrad Nitenpyram Suspending Concentrate.

Embodiment 2

[0026] Weigh 3.16g95% pyrenpyrad technical, 31.58g95% nitenpyram technical, 4g2700 (dispersant), 0.5gNNO (dispersant), 1g1004 (wetting agent), 1g ammonium chloride (disintegrant) , kaolin supplemented to 100g. After mixing evenly, perform jet milling, and then use water as a binder for granulation to prepare 33% tonamirad·nitenpyram water-dispersible granules.

Embodiment 3

[0028] Weigh 21.05g of 95% tonenpyrad TC, 21.05g of 95% nitenpyram TC, 4g of 2700 (dispersant), 0.5g of NNO (dispersant), 1g of 1004 (wetting agent), and make up to 100g of kaolin. After mixing evenly, carry out jet milling to make 40% tonenpyram·nitenpyram wettable powder.

Abstract

The invention discloses a pesticide composition, belongs to the technical field of pesticides, and solves the problems that the pesticide effect on preventing and treating cotton aphid is poor and the pesticide applying amount is great, so that pesticide residues exceed the standard range, the environment is polluted and the pesticide applying cost is high in the prior art. The pesticide composition disclosed by the invention comprises the following active ingredients: tolfenpyrad and nitenpyram in a weight ratio of (1 to 20) to (20 to 1). Compared with two single components, the pesticide composition is remarkably synergic, so that the preventing and treating effect is improved, the field use amount can be reduced to a great extent, the environment pollution and the pesticide residues are effectively reduced, and the cost is lowered. In addition, the two single components are different in action mechanisms and after the two single components are mixed in use, the insect resistance is overcome and the pest resistance to insecticides is delayed. The pesticide composition disclosed by the invention is low in toxicity, good in pesticide effect, quick to response and wide in disease preventing and treating range, not only can be used for preventing cotton aphids, but also can be used for preventing and treating injurious insects such as thrips, aleyrodids and mirids.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a pesticide composition and its application. Background technique [0002] Fenpyrad (Tolfenpyrad), chemical name: 4-chloro-3-ethyl-1-methyl-N-{[4-(4-methylphenoxy)phenyl]-methyl}-1H pyrazole -5-carboxamide is a new type of pyrazole heterocyclic insecticide, the main mechanism of action is to prevent the oxidative phosphorylation of insects, and it has the functions of killing eggs, inhibiting feeding, inhibiting oviposition and bactericidal. The drug has a wide insecticidal spectrum, and has a high control effect on various Lepidoptera, Hemiptera, Coleoptera, Thysanoptera, and Diptera pests. It is widely used in vegetables, fruit trees, flowers, tea and other crops. pest control. [0003] Nitenpyram, chemical name: (E)-N-(6-chloro-3-pyridylmethyl)-N-ethyl-N′-methyl-2-nitroethylenediamine, It is a neonicotinoid insecticide with excellent systemic property, penetrating effect...
