Embodiment 1

[0097]Embodiment 1 2% spirotetramat+3% pyridazinphos suspension concentrate

[0098] Spirotetramat 2% Pyridazinphos 3% Sodium methylnaphthalenesulfonate formaldehyde condensate 5% Dioctyl sodium sulfosuccinate 5% xanthan gum 0.3% Glycerol 5% Defoamer 0.6% water Top up to 100%

[0099] The active components, dispersant, wetting agent and water are mixed uniformly according to the ratio of the formula, and after grinding and / or high-speed shearing, 2% spirotetramat + 3% pyridazinate suspension concentrate is obtained.

Embodiment 2

[0100] Example 2 10% spirotetramat + 10% pyridazinphos wettable powder

[0101] Spirotetramat 10% Pyridazinphos 10% Sodium dodecyl sulfate 2% Sodium lignosulfonate 10% Silica 10% Kaolin Top up to 100%

[0102] The active ingredient, various additives and fillers are mixed according to the ratio of the formula, and after being pulverized by an ultrafine grinder, the wettable powder of 10% spirotetramat + 10% pyridafenthion is obtained.

Embodiment 3

[0103] Embodiment 3 10% spirotetramat+2% pyridazinphos aqueous emulsion

[0104] Spirotetramat 10% Pyridazinphos 2% N-Methylpyrrolidone 15% Sodium dodecyl benzene sulfonate 5% Phenylphenol polyoxyethylene ether 5% water Top up to 100%

[0105] Add the original drug, solvent and emulsifier together to dissolve into a uniform oil phase; mix the water-soluble components with water to obtain a water phase; mix the oil phase with the water phase under high-speed stirring to obtain a 10% spiral Tetrapetal + 2% pyridazinthion aqueous emulsion.

Abstract

The invention relates to a pesticide insecticidal composition containing spirotetramat and pyridaphenthion, and the insecticidal composition is highly effective for controlling harmful organisms. The pesticide insecticidal composition containing the spirotetramat and the pyridaphenthion contains the active ingredients, namely the spirotetramat and the pyridaphenthion, wherein the weight ratio of the spirotetramat to the pyridaphenthion is 50: 1-1: 50. The active compound combination disclosed by the invention has special systemic property, namely by using the insecticidal composition disclosed by the invention to perform treatment on seeds, the seeds can be protected, and plants obtained after germination can be further protected from being damaged by pests. Therefore, the immediate treatment of crops during seeding or slightly after seeding can be avoided; compared with various independent active compounds, the active compound combination disclosed by the invention has synergistically increased insecticidal activity; the insecticidal activity exceeds the sum of activities of two active compounds during respective application, so that the optimization of the quantity of the used active compounds becomes possible.

Description

technical field [0001] The present invention relates to a pesticide insecticidal composition containing spirotetramat and pyridazinate, the insecticidal composition is highly effective for controlling harmful organisms. Background technique [0002] Chemical control is an important means of preventing and controlling pests in agriculture. However, at present, effective control may not be possible due to poor effects, developed resistance, etc. due to the types of pests, their living characteristics, their living environment, and the like. [0003] Spirotetramat is a quaternary ketone compound, which belongs to the same class of insecticides and acaricides as spirodiclofen and spiromesifen of Bayer Company. Spirotetramat has unique action characteristics and is one of the modern insecticides with two-way systemic conduction performance. The compound can move up and down throughout the plant to reach the foliage and bark, thereby controlling pests such as on the inner leaves...
