Embodiment Construction

[0010] Test sample: Xanthium medicinal materials were purchased from Nanjing Pharmaceutical Co., Ltd.

[0011] Weeds tested: rape (Brassica rapa L. Chinensis Group), bermudagrass (Cynodon dactylon L.), duckweed (Lemna minor L.) seeds, provided by Hubei Academy of Agricultural Sciences.

[0012] Experimental instruments: high-speed universal pulverizer; vertical automatic pressure steam sterilizer; shaker; ultrasonic oscillator; rotary evaporator; constant temperature water bath; electronic balance; intelligent artificial climate box; vacuum pump.

[0013] experimental method:

[0014] When rapeseed and bermudagras seeds were used as screening targets for herbicidal activity screening, the agar medium surface coating method was used. Use a 96-well cell culture plate, add 300μL of water agar to each well, add about 10 seeds to each well, add 20μL of the drug solution, and the concentration of the primary screening sample is 1.0mg / mL, 0.3mg / mL, 0.1mg / mL . One week later, check the seed...

Abstract

The invention relates to pesticide filed, and particularly discloses a new application of a cocklebur fruit water extract in a weeding aspect, namely the cocklebur fruit water extract plays a complete inhibition role for brassica rapa L.Chinensis group under a certain concentration, and can be used as plant biological pesticides and weed killers.

Description

Technical field [0001] The invention relates to the field of pesticides, in particular to a new use of a water extract of Xanthium chinensis in weeding. Background technique [0002] There are 30,000 species of weeds widely distributed in the world, of which about 1,800 species cause varying degrees of damage to crops. The annual crop yield due to weed damage is as high as 9.7%. [0003] Although the use of chemical herbicides has effectively controlled many weeds, the extensive use of chemical agents has also caused many undesirable problems, such as the emergence of herbicide-resistant weed plants, soil pollution, water quality degradation, and harm to humans and livestock, etc. . [0004] With the improvement of people's environmental awareness and the need for sustainable agricultural development, the research on efficient, environmentally friendly, and harmless biological herbicides has attracted more and more attention. As a component of biological herbicides, plant-derived h...
