Problems solved by technology

[0006] (1) Liquid preparations mostly use different levels of organic solvents, which are likely to cause certain poisonous or critical damage to crops; in solid preparations, the powder has a low suspension rate, is easy to block the nozzle, and has a certain degree of dust hazard to the operator and the surrounding environment ;
[0007] (2) Most of the existing herbicides are used for soil spraying after potato planting and before emergence. This treatment method has an unsatisfactory control effect on weeds in the potato field and is not highly targeted;
[0008] (3) When the existing herbicides are applied to potatoes to control weeds, they have certain side effects on potatoes, poor safety, and have a certain inhibitory effect on their growth, thereby reducing crop yields

Abstract

The invention provides a herba patriniae extract containing herbicide. The herba patriniae extract containing herbicide contains the raw material ingredients in mass percentage: 6-13% of Metribuzin, 5-14% of herba patriniae extract, 7-12% of Triflumizole, 4-8% of Thifluzamide, 5-10% of Hexaconaole, 4-11% of Imidacloprid, 3-6% of dispersant, 2-5% of wetting agent, 1-5% of disintegrant, 2-6% of binder and the balance of filler. The invention also provides application of the herbicide in saline-alkaline-land potato planting. The herbicide and the application the herbicide have the beneficial effects that 30 days after the herbicide provided by the invention is applied, the prevention effect on common weeds, i.e., Echinochloa crusgalli, green bristlegrass, Solanum nigrum, acalypha copperleaf and Digitaria in potato fields respectively reaches 93.9-99.2%, 94.2-98.5%, 94.3-99.6%, 95.7-99.8% and 95.3-98.7%.

Description

technical field [0001] The invention relates to a herbicide and its application in potato planting in saline-alkali land, in particular to a herbicide containing Patrinia extract and its application in potato planting in saline-alkali land, belonging to the technical field of pesticides. Background technique [0002] Patrinia, the whole herb of Patrinaceae plant Patrinaceae, can be used as medicine, a perennial herb. Underground stems are slender and run horizontally, with special odor. The basal leaves are opposite, the leaves are lanceolate or ovate, 2~3 times pinnately parted, the central lobe is larger, elliptic or ovate, the lobes on both sides are narrow ovate to strip-shaped, both sides are sparsely covered with coarse hairs or nearly Glabrous, thyrses terminal, often 5-9 sequences into sparse corymbs; bracts small, flowers small, yellow, calyx not obvious, flowering period July-September. Animal experiments have shown that Patrinia extract can promote liver cell re...
