Abstract

The invention discloses an aphid insecticide in a paddy field and a preparation method thereof. The aphid insecticide comprises, by weight, 50 to 100 parts of tea seed cake, 30 to 50 parts of derris, 10 to 30 parts of pyrethrum, 8 to 25 parts of garlic, 2 to 10 parts of Chinese prickly ash, 2 to 4 parts of bamboo vinegar and 5 to 10 parts of a spray assistant. The aphid insecticide has high efficiency of killing aphids in the paddy field, does not produce chemical residues and is worthy of promotion.

Description

technical field [0001] The invention relates to the field of biological pesticides, in particular to a rice field aphid insecticide. Background technique [0002] Rice field aphid, insect name, belongs to Homoptera, Aphididae. Distributed in various wheat regions and some rice regions in China. In addition to the wheat long tube aphid, there are other kinds of aphids. Host in rice, wheat and so on. Adults and nymphs suck rice stems, leaves, and tender ears, which not only affect growth and development, but also secrete honeydew to cause soot, affecting photosynthesis and thousand-grain weight. Reduce production by 20% to 30%. [0003] In the south of the Yangtze River, aphids and nymphs with wingless fetuses survive the winter on the heart leaves or leaf sheaths of wheat plants and on weeds such as bluegrass, chrysalis, foxtail, etc. There is no obvious dormancy phenomenon. When the temperature is high, aphids can still be seen on the leaves. Eat on the surface. The ov...
