Embodiment 1

[0048] Example 1: 20.2% dithiocyanomethane·fluopyram suspending agent

[0049] Dithiocyanomethane 20%, Fluopyram 0.2%, Sodium methylnaphthalene sulfonate formaldehyde condensate 10%, Sodium lignosulfonate 10%, Xanthan gum 1%, Silicone oil 1%, Glycerol 5% , water topped up to 100%.

[0050]This embodiment is applied to control pepper root-knot nematode disease. Dilute the 20.2% dithiocyanomethane·fluopyram suspending agent with water at the dosage of 100g ai / ha (g ai / ha refers to the amount of active ingredient per hectare, the same as below), and control it 30 days and 60 days after the treatment The effects were 81.4% and 75.3%, respectively. 10% dithiocyanomethane suspending agent at 120 g ai / ha and 10% fluopyram suspending agent at 120 g ai / ha were used in the same way. The control effects of 10% dithiocyanomethane suspension at 30 days and 60 days were 71.2% and 40.2%, respectively; the control effects of 10% fluopyram suspension at 30 days and 60 days were 68.3% and 68...

Embodiment 2

[0051] Example 2: 30.3% dithiocyanomethane·fluopyram suspending agent

[0052] Dithiocyanomethane 0.3%, Fluopyram 30%, Nonylphenol Polyoxyethylene Ether Phosphate 8%, Carboxymethyl Cellulose 1%, Silica 1%, Glycerol 4%, water to make up to 100%.

[0053] This embodiment is applied to control tomato root-knot nematode. The 30.3% dithiocyanomethane·fluopyram suspending agent was diluted with water at 120 g ai / ha for root irrigation, and the control effects were 88.1% and 84.4% at 30 days and 60 days after treatment, respectively. 10% dithiocyanomethane suspending agent at 150g ai / ha and 10% fluopyram suspending agent at 150g ai / ha, used in the same way, 30 days and 60 days after 10% dithiocyanomethane suspending agent The control effects were 76.3% and 49.4%, respectively; the control effects of 10% fluopyram suspension after 30 days and 60 days were 73.4% and 70.3%, respectively. After the combination of dithiocyanomethane and fluopyram, the synergistic effect was obvious, an...

Embodiment 3

[0056] Example 3: 20% dithiocyanomethane·fluopyram aqueous emulsion

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

[0058] This embodiment is applied to control cucumber root-knot nematode. The 20% dithiocyanomethane·fluopyram aqueous emulsion was diluted with water at 120 g ai / ha, and the control effects were 94.1% and 89.7% respectively 30 days and 60 days after the treatment. 10% dithiocyanomethane EC at 150 g ai / ha and 10% fluopyram suspending agent at 150 g ai / ha were used in the same way. The control effects of 10% dithiocyanomethane EC at 30 days and 60 days were 76.2% and 46.3%, respectively; the control effects of 10% fluopyram suspension at 30 days and 60 days were 75.8% and 71.3%, respectively. %. After the combination of dithiocyanomethane and fluopyram, the synergistic effect was obvious, and the control effect on cucumber root-knot nematode w...

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 present invention relates to a pesticide composition, in particular to a nematicidal composition containing dithiocyanomethane. Background technique [0002] Plant parasitic nematodes mainly include: Meloidogyne, Ro tylenchulus, cyst nematodes (Heterodera), root patch nematodes (Pratykenchus). The direct feeding of nematodes can greatly reduce the absorption of nutrients and water by plants. Nematodes feed on plants to cause wounds and 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 attacking plants. Dithiocyanomethane has a killing effect on many bacteria, fungi and algae, and can also be used as a nematicide. However, when dithiocyanomethane is used alone, the effect is not ideal and the efficacy period is short. SUMMARY OF THE INVENTION [0004] The purpose of the present in...
