1. Prevent post-emergence herbicides of grasses weeds, high-efficiency grass cover, fine and stable killing, fine grasses, catching nets, collecting music, spray, etc., and controlling post-emergence herbicides of grass weeds, not suitable for Undergraduate plant turf use, this type of herbicide can also damage the lawn while controlling grass weeds.

2, after the prevention of broadleaf weeds, pesticides, herbicides, 2, 4, 4, 4, D, bentazon, herbaceous enemies, make it long, Huwei, Keqiling, good things, etc., not in nursery, garden , Ma Rong Golden Lawn application.
3, long-lasting herbicide sulfonylurea herbicides such as chlorsulfuron, metsulfuron, benzsulfuron, pyrazosulfuron, sulfonate, ethamsulfuron, nicosulfuron, etc.; imidazoline Ketone herbicides such as puerate; heterocyclic herbicides such as chlorpyrifos, chlorhexidine and the like. These herbicides have a long-lasting effect in the soil. In nurseries that have used these herbicides, flower seedlings planted after 3 years may be harmed. Metsulfuron-methyl will cause high fescue lawn spray, which will cause high fescue to yellow and die. Guangmingling causes whitening of turf plants.
4. Herbicide amides, ureas, and triazines of some herbicides which are toxic to soil and alachlor, acetochlor, oxachlor, sekzin, simazine, atrazine , rushing grass, cotton grass and so on. If these herbicides are applied on the lawn, the root system of the turf plants will be affected in the case of water accumulation, which will affect the development of the turf plants; in the continuous application, the soil structure will deteriorate and compact, affecting the soil around the roots of the turf plants. Ventilation, which in turn causes yellowing of turf plants.
5. Highly toxic or carcinogenic herbicides Sodium pentachlorophenol and paraquat are highly toxic and are absolutely prohibited in nurseries and lawns. Herbicide has been banned in many countries due to carcinogenesis, and China has been banned since 2000. Cables are carcinogenic to animals and should not be used. Fluoride has been banned in Europe due to carcinogenesis.
6. Herbicide with drifting pollution The problem of drifting pollution of herbaceous enemies and He Dazhuang is relatively large. Generally, there are flowers and seedlings around the lawn. Spraying herbicides such as herbicides and grasses on the lawn will affect the growth of surrounding flower seedlings.
7. Odors with odors such as the smell of 2 A 4 chlorine is irritating to humans. After inhalation, it has an effect on the stomach of the human body. It also causes phytotoxicity to the seedlings and should not be used.
8. Killer herbicides. For example, glyphosate (Nongda), paraquat (grass-free), etc., in the selection of herbicides, in addition to to prevent direct damage to the flower seedlings lawn, but also to prevent some potential, possible, hidden Sexual injury, so as not to cause irreparable damage to the yield, quality and surrounding environment of flowers, seedlings and lawns. In order to use, it should be noted that herbicides with broad spectrum of herbicides, moderate efficacy period, good eradication effect and no pollution are selected according to different needs, varieties and periods.
Although some seedlings have certain tolerance to low-dose glyphosate, sometimes glyphosate damage to seedlings is difficult to visually determine, and sometimes the damage is slow, and it is inevitable to spray glyphosate. There is drifting, which will cause damage to sensitive flower seedlings around.
It is not advisable to use herbicides on nursery lawns.
