Embodiment 1

[0033] Embodiment 1: aphidicide 1

[0034] What present embodiment provides is aphidicide 1, is made up of following composition by weight:

[0035] 50 parts of N-methylpyrrolidone, 10 parts of 6-methylcoumarin, 30 parts of turpentine, 10 parts of Tween 85 with an HLB value of 11.

[0036] Dissolve 6-methylcoumarin with N-methylpyrrolidone, then add Tween 85 with an HLB value of 11, and turpentine to dissolve and mix well to obtain aphidicide 1, which is used to control cotton aphids by spraying. The aphidicide of this embodiment can also control peach aphid, radish aphid, cabbage aphid or melon aphid.

Embodiment 2

[0037] Embodiment 2: aphidicide 2

[0038] What present embodiment provides is aphidicide 2, is made up of following composition by weight:

[0039] 50 parts of N-methylpyrrolidone, 5 parts of 6-methylcoumarin, 30 parts of turpentine, 10 parts of Tween 85 with an HLB value of 11.

[0040] Dissolve 6-methylcoumarin in N-methylpyrrolidone, then add Tween 85 with an HLB value of 11, and turpentine to dissolve and mix well to obtain aphidicide 2, which is used to control peach aphids by spraying. The aphidicide in this embodiment can also control cotton aphids, radish aphids, cabbage aphids or melon aphids.

Embodiment 3

[0041] Embodiment 3: aphidicide 3

[0042] What present embodiment provides is aphidicide 3, is made up of following composition by weight:

[0043] 50 parts of N-methylpyrrolidone, 15 parts of 6-methylcoumarin, 30 parts of turpentine, 5 parts of Tween 85 with an HLB value of 11.

[0044] Dissolve 6-methylcoumarin in N-methylpyrrolidone, then add Tween 85 with an HLB value of 11, and turpentine to dissolve and mix well to obtain aphidicide 3, which is used to control radish aphids by spraying. The aphidicide of this embodiment can also control cotton aphid, peach aphid, cabbage aphid or melon aphid.

Abstract

The invention discloses application of 6-methylcoumarin in an aphid killing agent and the aphid killing agent, and belongs to the field of pesticides, the 6-methylcoumarin aphid killing agent is usedfor killing leaf aphids, especially cotton aphids, peach aphids, radish aphids, cabbage aphids or melon aphids, and the aphid killing agent comprises 6-methylcoumarin, a solvent, an emulsifier and a solubilizer. Compared with other commercial aphids, the aphid killing agent containing the 6-methylcoumarin prepared by the invention has the advantages that the aphid killing effect is not similar, the development prospect and the application value are wide, and the aphid killing agent is an effective and feasible novel aphid killing agent. Meanwhile, the 6-methylcoumarin is wide in source, the preparation process is simple, the cost of the aphid killing agent is reduced, and popularization is facilitated.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to the application of 6-methylcoumarin in aphidicides and the aphidicides. Background technique [0002] Aphids, commonly known as greasy insects or honey worms, belong to the order Hemiptera (formerly the order Hemiptera), including the superfamily Adelgoidea and the superfamily Aphidoidea. Aphids are mainly distributed in temperate and subtropical regions of the northern hemisphere, and are rarely distributed in tropical regions. At present, there are more than 4,700 species of aphids known in the world. Aphids vary in size, from one to ten millimeters in length. Aphids feed on plant juice, and at the same time, the abdominal tube discharges a rapidly hardening defense fluid, which not only hinders plant growth, forms galls, spreads viruses, but also causes deformities in flowers, leaves, and buds. for plant pests. Its life history is complex, most species are oligophagous or monophag...
