Some common herbicides for potatoes are briefly described as follows:
Commonly used soil treatment herbicides; 1. Duer, the common name of metolachlor, the dosage is 72% Duer emulsifiable concentrate 0.1~0.23 liters/mu, mixed with Sike and other broadleaf herbicides, can expand the spectrum of killing grass . 2. Wones, the common name acetochlor, the usual dose is 50% acetochlor EC 0.15 ~ 0.2 liter / acre, 90% acetochlor EC 0.09 ~ 0.12 liter / acre. 3. Pulebao, the common name of isopropyl oxalate, the dosage is 72% Pulebao emulsifiable concentrate 0.1~0.23 liters/mu. 4. Fluorine, the common name of trifluralin, its volatile and photolysis, must be mixed with soil. When using, the dosage is determined according to the soil organic matter content. The general dosage is 48% trifluralin emulsifiable concentrate 0.1~0.13 liter/mu.
Post-emergence herbicide: Baocheng, the general name of sulfamesulfuron, the dosage is 25% Baocheng dry suspension agent 5~6g/mu, the best period of application is potato emergence, grass weed 2~4 At the leaf stage, broadleaf weeds are less than 5 cm high and most weeds have emerged. After applying Baocheng, the lower jaw cannot grow sensitive crops such as rapeseed and flax.
The use of herbicides should be determined according to the soil organic matter content. Under normal circumstances, the organic matter content (fertile) can be appropriately applied. Conversely, the soil organic matter content can be reduced appropriately; the clay should be applied more, and vice versa. Sand land should be applied less. Keep the soil moist when applying the herbicide, and moisten the soil surface to improve the herbicidal effect of the herbicide. In areas with high winds in the north, in order to improve the adsorption of herbicides on the surface, 1%~2% high-quality detergent or washing powder can be added to the herbicide solution.

A Workstation sink is a sink with a mechanism built in to the front and back sides of the bowl to allow accessories to sit on the step or ledge, affording the user to prepare meals on the sink instead of on the countertop.
