Embodiment 1

[0048] Embodiment 1: 20.2% dithiocyanomethane fluopyram suspension concentrate

[0049] Dithiocyanomethane 20%, fluopyram 0.2%, sodium methylnaphthalene sulfonate formaldehyde condensate 10%, sodium lignosulfonate 10%, xanthan gum 1%, silicone oil 1%, glycerol 5% , make up to 100% with water.

[0050]This embodiment is applied to the prevention and treatment of capsicum root-knot nematode. Dilute the 20.2% dithiocyanomethane fluopyram suspensible concentrate with 100g ai / ha (g ai / ha refers to the amount of active ingredients per hectare, the same below) and dilute the ground with water for 30 days and 60 days after the application. The effects are 81.4% and 75.3% respectively. 10% dithiocyanomethane suspending agent is used at 120g ai / ha and 10% fluopyram suspending agent is used at 120g ai / ha in the same way. The control effects of 10% dithiocyanomethane suspension concentrate on 30 days and 60 days were 71.2%, 40.2% respectively; 63.4%. The compounding of dithiocyanomet...

Embodiment 2

[0051] Embodiment 2: 30.3% dithiocyanomethane fluopyram suspension concentrate

[0052] Dithiocyanomethane 0.3%, fluopyram 30%, nonylphenol polyoxyethylene ether phosphate 8%, carboxymethyl cellulose 1%, white carbon black 1%, glycerol 4%, water to make up to 100%.

[0053] This embodiment is applied to control tomato root-knot nematode. Dilute 30.3% dithiocyanomethane·fluopyram suspension concentrate with 120g ai / ha and dilute with water for root irrigation treatment, and the control effects are 88.1% and 84.4% at 30 days and 60 days after treatment. 10% dithiocyanomethane suspension at 150g ai / ha and 10% fluopyram suspension at 150g ai / ha, use the same method, 10% dithiocyanomethane suspension 30 days and 60 days after treatment The control effects were 76.3% and 49.4% respectively; the control effects of 10% fluopyram suspension were 73.4% and 70.3% at 30 days and 60 days after treatment. The compounding of dithiocyanomethane and fluopyram has obvious synergistic effect,...

Embodiment 3

[0056] Embodiment 3: 20% dithiocyanomethane fluopyram aqueous emulsion

[0057] Dithiocyanomethane 10%, fluopyram 10%, N-methylpyrrolidone 10%, calcium dodecylbenzenesulfonate 5%, Nongru 600# 5%, water to make up to 100%.

[0058] This embodiment is applied to control cucumber root-knot nematode. Dilute the 20% dithiocyanomethane fluopyram aqueous emulsion at 120g ai / ha with water to shower the ground, and the control effects are 94.1% and 89.7% at 30 days and 60 days after application. 10% dithiocyanomethane emulsifiable concentrate is used at 150g ai / ha and 10% fluopyram suspending agent is used at 150g ai / ha in the same way. The control effects of 10% dithiocyanomethane emulsifiable concentrate were 76.2% and 46.3% after 30 days and 60 days respectively; %. The compounding of dithiocyanomethane and fluopyram has obvious synergistic effect, and the control effect on cucumber root-knot nematode is obviously better than that of single agent.

Abstract

A nematode insecticidal composition. The invention relates to a nematode insecticidal composition, effective components of which contain dithiocyano-methane (A) and fluopyram (B). The mass ratio of (A) to (B) is 100:1-1:100. After complex formulation of (A) and (B), the nematode insecticidal composition has obvious synergism. The nematode insecticidal composition is used in nematode control for plants and places of fruit trees, vegetables, grain crop, oil crops, sugar crops, linen-cotton crops, gardening plants and the like.

Description

technical field [0001] The invention relates to a pesticide composition, especially a nematicidal composition containing dithiocyanomethane. Background technique [0002] Plant parasitic nematodes mainly include: Meloidogyne, Ro tylenchulus, 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. Dithiocyanomethane has a killing effect on many bacteria, fungi, and algae, and can also be used as a nematicide. However, dithiocyanomethane is not ideal when used alone, and the drug effect period is short. Contents of the invention [0004] The object of the present invention is to...
