Problems solved by technology

The 3rd to 4th instar larvae feed and cause holes and nicks. In severe cases, the vegetable leaves are eaten into a net, which reduces the edible value of the vegetable.
Extensive use of organic solvents not only causes a waste of chemical raw materials, but also poses a great threat to the environment and human health

Embodiment 1

[0018] Embodiment 1, methomyl 15kg and abamectin 0.5kg are dissolved in the cyclohexanone 10kg, then drop into 700 # 6kg, AEO-9 7kg, and JFC 0.5kg were fully stirred evenly, then put into a homogenizer equipped with 61kg of dispersion medium water to be vigorously mixed and homogenized, and finally obtained 15.5% methomyl·abamectin microemulsion. The aforementioned microemulsion was diluted 1000 times and sprayed. According to the method of Experimental Example 1, the control effect on Plutella xylostella was 95% one day after the application, and 87% after seven days. 1500 times of liquid of microemulsion produced by the present invention is used to prevent and control longan psyllid, and the control effect is 94% after three days of application, and 91.6% after seven days.

Embodiment 2

[0019] Embodiment 2: methomyl 20kg and avermectin 0.5kg are dissolved in DMF 10kg, in the cyclohexanone 5kg, then drop into 700 # 7kg, Tween-80 6.5kg, and Azone 0.5kg are fully stirred evenly, and then put into a homogenizer equipped with 50.5kg of dispersion medium water to be vigorously mixed and homogenized, and finally 20.5% methomyl Avermectin is obtained Vegetable microemulsion. The foregoing microemulsion was diluted 1500 times and sprayed. According to the method of Experimental Example 1, the result was 96.5% of thrips control effect on vegetables one day after the medication, and 88.4% after seven days of medication.

Embodiment 3

[0020] Embodiment 3: methomyl 15kg and abamectin 0.3kg are dissolved in the cyclohexanone 10kg, then drop into 500 # 5.5kg, AEO-9 6kg, and Azone 0.5kg are fully stirred evenly, and then put into a homogenizer equipped with 62.7kg of dispersion medium water to be vigorously mixed and homogenized, and finally 15.3% methomyl·abamectin is obtained Microemulsion. The aforementioned microemulsion was diluted 1500 times and sprayed. According to the method of Experimental Example 1, the control effect on whitefly on tomato was 87.6% after one day of medication, and 82.9% after seven days of medication.

Abstract

A kind of insecticide composition in micro emulsion type mainly consists of methoyl 10-30%, abamectin 0.1-2%, solubilizing agent 5-30%, and emulsifying agent 5-20%, water 20-80%. The micro emulsion is a strong absorbable insecticide with high efficiency and low toxicity. It has very good preventing and killing effect to diamondback moth on mustard family, moreover, it is effective to some other destructive insects with stab absorbed type. Acrape absorbed type mouth parts, sucbas aphid, thrips, white louse, mite.

Description

technical field [0001] The invention relates to a pesticide, in particular to a methomyl-abamectin microemulsion. Background technique [0002] Diamondback moth [Plutella xylastella (L.)] belongs to Lepidoptera, Plutellaidae, and is distributed all over the world. It occurs commonly in Africa, Europe, America, and Asia. It occurs in all provinces of my country, but it occurs more in southern provinces. Plutella xylostella mainly feeds on cruciferous plants, but it can also damage other plants such as tomatoes, ginger, and potatoes. Plutella xylostella uses larvae to damage the leaves. The early instar larvae can drill into the leaf tissue to feed on the mesophyll, and when they are slightly larger, they can eat the epidermis and mesophyll of the leaf to form a transparent spot. The 3rd to 4th instar larvae feed and cause holes and nicks. In severe cases, the vegetable leaves are eaten into a net, which reduces the edible value of the vegetable. In the seedling stage of veg...
