Problems solved by technology

Iprodione is a low-toxic fungicide that is effective against many fungal diseases. It has been found that Iprodione has certain killing activity against plant nematodes, but the effect of Iprodione alone is not ideal, and it is easy to induce nematodes to develop resistance , is not conducive to continuous control

Embodiment 1

[0054]Embodiment 1: 16.2% iprodione·abamectin suspension

[0055] Iprodione 16%, Abamectin 0.2%, Sodium Naphthalene Sulfonate Formaldehyde Condensate 10%, Sodium Lignosulfonate 10%, Xanthan Gum 1%, Silicone Oil 1%, Glycerol 5%, Water Top up to 100%.

[0056] This embodiment is applied to the prevention and treatment of capsicum root-knot nematode. Dilute the 16.2% iprodione·abamectin suspension concentrate with 800g·a.i. / ha (g·a.i. / ha refers to the amount of active ingredients per hectare, the same below) and add water to dilute the ground, 10 days and 20 days after the drug, the control The effects are 88.5% and 87.3% respectively. 25% iprodione suspension concentrate is used at 1000g·a.i. / ha and 1.8% abamectin emulsifiable concentrate is at 80g·a.i. / ha, and used in the same way. The 10-day and 20-day control effects of 25% iprodione suspension were 58.1% and 54.2% respectively; the 1.8% abamectin EC 10-day and 20-day control effects were 64.7% and 60.6% respectively. The...

Embodiment 2

[0057] Embodiment 2: 24% iprodione·abamectin suspension

[0058] Iprodione 23%, Abamectin 1%, Nonylphenol Polyoxyethylene Ether Phosphate 8%, Carboxymethyl Cellulose 1%, Silica 1%, Glycerin 4%, Water to 100% .

[0059] This embodiment is applied to control tomato root-knot nematode. Dilute 24% iprodione·abamectin suspension concentrate with water at 450g·a.i. / ha for root irrigation treatment, and the control effects are 93.5% and 90.2% at 10 days and 20 days after treatment. 25% iprodione suspension was used at 800g a.i. / ha and 1.8% abamectin emulsifiable concentrate was used at 100g a.i. / ha in the same way, and the control effect of 10% iprodione suspension was 10 days and 20 days after treatment 63.3% and 51.7% respectively; 10 days and 20 days after 1.8% avermectin emulsifiable cream drug, the control effects were 75.4% and 71.6% respectively. 20 days investigation after medicine finds simultaneously, the damp blight incidence rate that 24% iprodione · abamectin suspensi...

Embodiment 3

[0062] Embodiment 3: 20% iprodione·profenofos emulsion in water

[0063] Iprodione 15%, profenofos 5%, N-methylpyrrolidone 10%, calcium dodecylbenzenesulfonate 5%, Nongru 600# 5%, water to make up to 100%.

[0064] This embodiment is applied to control cucumber root-knot nematode. Dilute 20% iprodione·profenofos emulsion in water at 800g·a.i. / ha and add water to shower the ground, and the control effects are 89.7% and 86.3% at 10 days and 20 days after application. 50% iprodione wettable powder is used at 1200g·a.i. / ha and 40% profenofos emulsifiable concentrate is used at 1000g·a.i. / ha in the same way. The control effects of 50% iprodione water dispersible granule were 56.2% and 50.2% after 10 days and 20 days respectively; the control effects of 40% profenofos emulsifiable concentrate were 70.8% and 64.3% after 10 days and 20 days respectively . The synergistic effect of the combination of iprodione and profenofos is obvious, and the control effect on cucumber root-knot n...

Abstract

The invention relates to a nematicide composition which comprises effective ingredients such as iprodione (A) and the other active ingredient (B) by mass ratio of 80:1-1:80, wherein (B) is fosthiazate, profenofos, avermectin, azadirachtin or dithiocyano-methane. In the invention, A is recomposed with B, thus having obvious synergistic effect. The composition is applied to pest control on crops such as fruit trees, cotton, wheat, paddy rape, vegetables, flowers and the like, especially for nematode control.

Description

technical field [0001] The invention relates to a pesticide composition, especially a nematicidal composition containing iprodione. 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. At present, chemical control largely relies on highly toxic pesticides such as methimaphos, thiamephos, and carbofuran, which poses great environmental concerns, and there are few low-toxic nematicides to choose from. Iprodione is a low-toxic fungicide that is effective against many fungal diseas...
