What kind of herbicide does Salvia miltiorrhiza use

At present, most of the planting methods of Salvia miltiorrhiza are seed propagation, which is a perennial plant, and the growth cycle is relatively long, so weeding in the field is very important. So what kind of herbicide does Salvia miltiorrhiza use?

1. Trifluralin: chemical weeding soil treatment with trifluralin during weed germination. Because the dosage is small and trifluralin is a low-grade herbicide, it has little effect on the growth of Salvia miltiorrhiza, but its pharmacology can only have a good effect on monocotyledonous weeds and dicotyledonous broad-leaved weeds. Growers are eager for herbicides which not only have better control effect on Gramineae broad-leaved weeds, but also have no side effects on Salvia miltiorrhiza.

two。 Quizalofop removes the inactive L-body and the remaining active isomer (R-body) in the two optical isomers, so it has the same action mechanism and herbicide spectrum as quinoline, but because it improves plant absorption and mobility, the action speed is fast and the efficacy is stable. it is not easily affected by environmental conditions such as Rain Water, air temperature, humidity and so on. The solution is absorbed through the stems and leaves of weeds, conducts upward and downward in the plant, accumulates in the apical and intermediate meristem, inhibits the synthesis of cellular fatty acids, thus causing weed necrosis.

Radix Salviae Miltiorrhizae had better be pulled out manually, which is more beneficial to the growth of Salvia miltiorrhiza. The effect of artificial extraction of Salvia miltiorrhiza is relatively low, and it is easy to relapse. The two weeding methods have their own advantages.
