Embodiment 1

[0019] The tested insects: cotton bollworm (Heliothis armigera), diamondback moth (Plutella xylostella) and bean aphid (Aphis craccivora), provided by Hubei Academy of Agricultural Sciences.

[0020] Test method: When Plutella xylostella and cotton bollworm were used as test insects, the eggs were sterilized with 10% formaldehyde solution for 15 minutes, and the improved feed formula of Liang Gemei of Beijing Academy of Agricultural Sciences was adopted, and the eggs were artificially raised indoors. Feeding conditions: temperature 25°C, relative humidity 75%-85%. Dilute the sample to a certain concentration and spread it on the surface of the artificial feed. A 96-well cell culture plate was used, and 300 μL of artificial feed and 20 μL of diluted drug solution were added to each well, and the experimental results were checked one week later. The concentration of the drug solution in the initial screening is 1.0 mg / mL, and the concentration in the secondary screening is adju...

Embodiment 2

[0024] Bacteria to be tested: Pythium ultimum, Botrytis cinerea, Septoria nodorum, Alternaria Solani, Fusarium culmorum, R. blight ( Rhizoctonia solani), provided by Hubei Academy of Agricultural Sciences.

Abstract

The invention discloses application of a poria cocos ethanol extract to biopesticides and particularly relates to application of the poria cocos ethanol extract to killing with poison of cotton bollworm and resistance to wheat glume blight and early blight of plants. The poria cocos ethanol extract provided by the invention is capable of effectively killing the cotton bollworm with poison and resisting the wheat glume blight and the early blight of plants, and the selection range of the biopesticides is broadened.

Description

technical field [0001] The invention relates to a new application of the ethanol extract of poria cocos, in particular to the application of the ethanol extract of poria cocos in pesticides. Background technique [0002] Cotton bollworm (Heliothis armigera) is a Lepidoptera Noctuidae insect with a wide range of hosts and strong reproductive ability. It is one of the main pests that damage cotton and other crops in Asia, Oceania, Africa and Europe, and is a worldwide crop pest. Since the 1990s, the annual frequency of cotton bollworm outbreaks in major cotton producing areas such as the Yellow River, Yangtze River, Liaohe River and Xinjiang has increased significantly, resulting in a cotton yield reduction rate of 35-50%, and some fields in some areas even have no harvest. [0003] Septoria nodorum is one of the main pathogens causing wheat glume blight, which mainly damages immature spikes and stems of wheat, and also damages leaves and leaf sheaths. After the ear is infect...
