Embodiment 1

[0026] Embodiment 1, thiazophosphine dinotefuran wettable powder

[0027] Thiazophosphine 10%, dinotefuran 2%, calcium lignosulfonate 5%, sodium lauryl sulfate 2.6%, white carbon black 2.4%, phenyl phosphite 2.3%, kaolin 33%, diatomaceous earth 42.7% , after pulverization and mixing, the active ingredient is 12% thiadizuron · dinotefuran wettable powder.

Embodiment 2

[0028] Embodiment 2, thiazophosphine flupyrfurone suspension concentrate

[0029] Thiazophosphine 10%, fluoropyrrofurone 2%, furfural 1%, polyoxyalkylphenyl ether ester phosphate 3.6%, propylene glycol 12%, xanthine 0.2%, polyalkylpolysiloxane 0.1%, water 71.1 %, using wet pulverization until the average particle size reaches 3±0.5 μm of the volume average particle size, and the active ingredient is 12% thiazophosphine-flupyrfurone suspension concentrate.

Embodiment 3

[0031] Test time: March 10, 2017--July 16, 2017

[0032] Experimental site: Anyang City Vegetable Institute semi-basement solar greenhouse, the last crop is cucumber, and the occurrence of root-knot nematodes is relatively serious.

[0033] Test plan: Compound thiazophosphine and dinotefuran in a certain ratio to make active ingredient ratios of 100:0, 100:1, 100:2, 100:5, 100:10, 100:20, 100:50, etc. Seven kinds of granules with 10% thiazolylphosphine or 10% total effective content of thiazolylphosphine and dinotefuran, each ratio was repeated twice, and the dosage per mu was 1000 grams for spreading.

[0034] Test operation

[0035] Transplanting is carried out during the period of 2-3 leaves and 1 heart of tomato seedlings. Before transplanting, spray the prepared medicinal solution on the dug seedling holes with a sprayer. Observe within 1-2 weeks after transplanting whether the pesticide has an effect on the slow seedling growth of tomato seedlings. After the tomato w...

Abstract

The invention belongs to the field of pesticides, in particular to a thiazophosphine composition containing neonicotinoid insecticidal components. Its active ingredients are: neonicotinoid insecticidal ingredients and thiazophosphine. The mass ratio of thiazophosphine to neonicotinoid insecticidal components can be: 100:1-100:50. The present invention studies the compounding of nicotine furan and thiazole phosphine, and finds that the compounding of neonicotinoid insecticidal components and thiazolyl phosphine shows a good active effect, and the compounding of nicotine furan and thiazole phosphine can effectively slow down the action of thiazole The growing problem of resistance to phosphine.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a thiazophosphine composition containing neonicotinoid insecticidal components. Background technique [0002] New types of nicotine (chloronicotine and thionicotine) mainly bind to acetylcholinesterase receptors, and inhibit the activity of nicotinic acetylcholine receptors on the post-synaptic membrane of nerve cells, thereby showing their toxic effects on insects. Compared with other neurotoxins that act on acetylcholine receptors, neonicotinoids have two binding sites, cationic and anionic, that bind to acetylcholinesterase receptors in the molecule. [0003] For a long time, the new nicotine must have a nitrogen-containing aromatic ring equivalent to the nicotine pyridine ring, the anionic structure of chloronicotine is a chloropyridine ring, and the anionic structure of thionicotine is a chlorine-containing thiopyridine ring. Compared with chloronicotinoids (imidacloprid, thiaclop...
