How to choose potato seedling herbicide

After the potato seedlings, the potato has already emerged. At this time, the vitality of the weeds is extremely strong. If the herbicides are not good, the seedlings may be killed, but the grass is not dead. So how to choose the potato seedlings and the herbicides have been many people. Concerns. China Agricultural Resources Network briefly introduces several potato seedling herbicides:
At present, the common herbicides for potato seedlings are mainly sulfuron-sulfuron, and the effects of single drugs such as oxazinone are not very good. For example, the compounding has already antagonized, and now there are sulfensulfuron-methyl, citricin, and oxazinone. The effect of compounding is good, and it is not affected by the growth of potatoes.

Focus on two potato seedling herbicides:
1. Gore. The drug is a herbicide for selective contact-type soil treatment with post-emergence stem and leaf treatment. Use 24% of Gore's cream 40-50ml to spray 60kg of water evenly, which can prevent weeds, thousand gold, goosegrass, foxtail, hard grass, bluegrass, purslane, iron leek, alfalfa, alfalfa (Grey) and other annual weeds, but the effect on perennial weeds is poor. When using it, it should be noted that: 1 When using it for the first time, it should be carried out according to different climatic zones, and the small-scale test should be carried out to find the best application method and the optimum dosage suitable for local use, and then use it in a large area. 2 Gore is a contact-killing herbicide, spray the drug evenly and thoughtfully, do not destroy the drug film layer after spraying, the dosage should be accurate.
2. Saikejin. The drug is a selective systemic soil treatment agent. Use 70% Saikejin wettable powder 25~65g to spray 40~50kg of water evenly on the table, which can prevent a variety of broadleaf weeds and some grass weeds, such as 藜 (gray), 寥, Purslane, bitter leeks, sorghum, cocklebur, valerian, foxtail, etc. When using it, it should be noted that it is easy to produce phytotoxicity when it is exposed to large rainfall or flooding after application.
Of course, if you can manually weed, then it is best, no need to choose

Stainless Steel Twill Weave Mesh is a kind of wire cloth product with flat and smooth mesh, uniform mesh, no deformation, good extensibility and abrasion resistance. Twill weave Stainless Steel Mesh warp and weft threads interwoven from the adjacent strands - weaving in the direction of silk and shuttle.The movement of this upper and lower knitting is the movement of the shuttle.Twill weaving can be used to weave different specifications of mesh and mesh screen. 

Material: 201, 304, 304 (L), 310, 316 (L), etc

Features: Features: stainless steel twill weave net is an acid, alkali resistant, high temperature, tensile and wear resistance strong product, has the filtering precision, the load strength high characteristics.

USES: Twill weave stainless steel mesh is widely used in aerospace, petroleum, chemical industry, scientific research and transportation, etc, used in acid, alkali environment conditions screening and filter, oil industry as mud mesh, chemical fiber industry as screen mesh, plating industry as pickling nets.

Extra tip: Stainless steel twill wire mesh gauge packaging must be strict, outer waterproof paper - moistureproof film - cushion film - cardboard packaging products in order to prevent wooden - damp impact in the transport process.
