Problems solved by technology

However, the dosage of thiazophosphine used alone is large, and long-term use will inevitably induce nematode resistance, which is not conducive to continuous control

Embodiment 1

[0046] Embodiment 1: 10.2% thiazophos-abamectin suspension concentrate

[0047] Thiazophosphine 10%, Abamectin 0.2%, Sodium Naphthalene Sulfonate Formaldehyde Condensate 10%, Sodium Lignosulfonate 10%, Xanthan Gum 1%, Silicone Oil 1%, Glycerol 5%, water to make up to 100%.

[0048]This embodiment is applied to the prevention and treatment of capsicum root-knot nematode. Add water to dilute 10.2% thiazophosphine abamectin suspension concentrate by 1020g a.i. / ha (g a.i. / ha is the amount of active ingredients per hectare) and drench the ground, and the control effects of 10 days and 20 days after the drug are respectively 85.5 %, 84.2%. 15% Thiazophosphine Suspension Concentrate at 1500g·a.i. / ha and 1.8% Abamectin EC at 80g·a.i. / ha, used in the same way. The 10-day and 20-day control effects of 15% thiazophosphine suspension were 76.1% and 73.2% respectively; the 10-day and 20-day control effects of 1.8% abamectin EC were 71.7% and 64.6% respectively. Thiazophosphine and abam...

Embodiment 2

[0049] Embodiment 2: 24% thiazophosphine azadirachtin suspension concentrate

[0050] Thiazophosphine 20%, azadirachtin 4%, nonylphenol polyoxyethylene ether phosphate 8%, carboxymethyl cellulose 1%, white carbon black 1%, glycerin 4%, and water to make up to 100%.

[0051] This embodiment is applied to control tomato root-knot nematode. Dilute the 24% thiazophosin. azadirachtin suspension concentrate with water at 300g·a.i. / ha and soak the roots for 12 hours. The control effects are 91.5% and 86.2% at 10 days and 20 days after treatment. 10% thiazophosphine emulsifiable concentrate is pressed 1000g·a.i. / ha and 8% azadirachtin suspension is pressed 70g·a.i. / ha, is used in the same way, and the control effect of 10% thiazophosphine suspension agent after 10 days and 20 days is 72.3 respectively. %, 66.3%; the control effects of 8% azadirachtin suspension were 67.4%, 65.6% in 10 days and 20 days after treatment. The compounding of thiazophos and azadirachtin has obvious synerg...

Embodiment 3

[0054] Embodiment 3: 20% thiazophos-abamectin aqueous emulsion

[0055] Thiazophosphine 15%, Abamectin 5%, N-Methylpyrrolidone 10%, Calcium Dodecyl Benzene Sulfonate 5%, Nongru 600# 5%, water to make up to 100%.

[0056] This embodiment is applied to control cucumber root-knot nematode. Dilute the 20% thiazophosphine-abamectin aqueous emulsion at 600g·a.i. / ha with water, and the control effects are 91.7% and 86.3% at 10 days and 20 days after application. 60% thiazophosphine water dispersible granules are used in the same way at 1500 g·a.i. / ha and 5% abamectin emulsifiable concentrate at 300 g·a.i. / ha. The control effects of 60% thiazole phosphine water dispersible granule were 73.2% and 68.2% after 10 days and 20 days respectively; the control effects of 8% abamectin EC were 80.8% and 74.3% after 10 days and 20 days respectively . Thiazophosphine and abamectin have obvious synergistic effect after compounding, and the control effect on cucumber root-knot nematode is obviou...

Abstract

The invention relates to a pesticide composition comprising the active components including (A) which is fosthiazate, and (B) which is at least one of abamectin and azadirachtin. The mass ratio of A to B is 100:1-1:50. By combining A and B, the composition has obvious synergistic effect and is used for controlling the pests on such crops as fruit trees, cotton, wheat, rice, rape, vegetables, flowers and the like, especially for controlling nematodes.

Description

technical field [0001] The invention relates to an insecticidal composition, especially a pesticide composition containing thiazophosphine. Background technique [0002] Plant parasitic nematodes mainly include: Meloidogyne, Rotylenchulus, cyst nematodes (Heterodera), root spot nematodes (Pratykenchus). The direct feeding of nematodes can greatly reduce the absorption of nutrients and water by plants. The nematodes feed on plants and cause wounds, which also facilitate the invasion of plant pathogens. [0003] At present, there are not many options for chemical control of nematodes, and the control of nematodes in agriculture basically focuses on preventing nematodes from invading plants. Once a plant is parasitized, it will inevitably cause damage to the plant, so it is advantageous to provide a new nematode control composition to prevent or reduce nematode damage. [0004] At present, for nematode control, highly toxic pesticides such as methimaphos, thiamephos, and carb...
