Abstract
The invention belongs to the technical field of field weed control, and particularly relates to application of a plant source active substance stephanine in weed control. The research of the invention discovers that the stephanine can effectively inhibit the growth of the bud length and the root length of barnyard grass, special-shaped nutgrass and spanishneedles herb, and has the most obvious effect of inhibiting the growth of the bud length and the root length of barnyard grass. Compared with barnyard grass, the inhibition effect of the stephanine on the bud length and the root length of the sedge, the spanishneedles herb is slightly weaker, but the comparison shows that the inhibition effect of the stephanine with high concentration or low concentration on the bud length and the root length of the sedge is better than that of the herbicide pretilachlor under the same condition, and the stephanine is more green and efficient.
Description
Technical Field
The invention belongs to the technical field of field weed control, and particularly discloses application of a plant source active substance stephanine in weed control.
Background
There are about 580 weeds in China's farmland, 129 weeds in paddy field. Weed clusters can lead to reduced crop yields and quality, and weeds must be controlled. Currently, commercial herbicides are mainly chemical herbicides, such as dichloroacetamides, carboxylic acid derivatives, oxime ethers, thiazole carboxylic acids, triazoles, dihydropyrazole dicarboxylic acids, and the like. However, the long-term and large-scale use of chemical herbicides leads to the rapid development of weed resistance, such as barnyard grass and stephania japonica resistance, which is a threat to rice yield.
The plant source herbicide is active matter extracted from plant and possessing herbicidal effect. There are now hundreds of natural compounds found in the world that have herbicidal activity. Therefore, the method for widely screening natural products with herbicidal activity in plants, directly developing the natural products into biogenic herbicides, or carrying out structural derivation and optimization is one of effective ways for solving the problem of environmental compatibility. Cepharanthine is an active chemical component of the traditional Chinese medicine Cepharanthine, has various treatment effects on human bodies, but has few reports on the application in field weed control.

The present invention also provides a herbicide, the component comprises cepharanthine, and the cepharanthine is usually formulated as a herbicide component in various ways by using formulation aids such as solvents, carriers and the like.
The herbicide acts primarily on field weeds, preferably the weeds include grasses, sedge and broadleaf weeds.
Preferably, the weeds are barnyard grass, cyperus rotundus of the family cyperaceae, and spanishneedles herb; more preferably barnyard grass.
Preferably, the concentration of the stephanine is 0.00019531 g/L-0.05 g/L.
The herbicide may be prepared in various formulation forms, such as powders, gels, water-dispersible granules, water-dispersible tablets, wettable powders, effervescent compressed tablets, emulsifiable concentrates, microemulsions, aqueous emulsions, flowable oils, water-dispersible granules, suspoemulsions, microcapsule suspensions, emulsion granules, solutions, and the like.
Compared with the prior art, the excellent effects of the invention are mainly reflected in the following aspects:
the invention provides a new application of a plant source active substance stephanine, which can effectively prevent and control weeds. The stephanine has inhibiting effect on barnyard grass, special-shaped nutgrass flatsedge and spanishneedles herb in weeds, and especially has the strongest inhibiting effect on barnyard grass. The invention provides a new technical scheme for green weed treatment and agricultural sustainable development.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The preparation is carried out according to the conventional conditions or the conditions suggested by manufacturers without specifying the specific conditions in the examples of the invention, and the reagents or instruments used are conventional products which can be obtained through commercial purchase without specifying the manufacturers.
1. Test materials and methods
1.1 test Agents
Stephanine, pretilachlor and acetic acid.
1.2 testing weeds
Barnyard grass, special-shaped nutgrass and spanishneedles herb.
1.3 test methods
Pre-emergence treatment of weeds in petri dishes
Spreading three kinds of weed seeds of barnyard grass, special-shaped nutgrass and spanishneedles uniformly on the wet filter paper, and accelerating germination at 28 ℃. And selecting 20 seeds of three weed seeds with consistent bud length, and uniformly spreading the seeds in a culture dish for later use. 2.5mg of stephanine is dissolved in 50mL of 0.025% acetic acid water to prepare the high concentration of 0.05g/L. The high concentration was diluted with 0.025% acetic acid water to five concentrations of 0.025, 0.0125, 0.003125, 0.00078125, 0.00019531. 3mL of soaked barnyard grass, special-shaped nutgrass and spanishneedles herb seeds are taken, and after treatment, the barnyard grass, the special-shaped nutgrass and the spanishneedles herb seeds are placed in a climatic chamber for cultivation (14 h in daytime, 28 ℃,80% RH; 10 h at night, 25 ℃ and 75% RH). Each treatment was repeated 3 times. After 7d treatment, the inhibition rate of the medicines on the bud length and root length of barnyard grass, special-shaped nutgrass and spanishneedles herb is counted.
