When using herbicides, be aware that many herbicides should not be used in gardens, flower nurseries and lawns.
1. Post-emergence herbicides for controlling broadleaf weeds. 2 A 4 chlorine, 2,4-D, bentazon, herbaceous enemies, make it long, Hu Wei, Ke Qi Ling, Hao Shi Da, etc., can not be applied in nursery, garden, horseskin golden lawn.
2. Prevent post-emergence herbicides for grass weeds. High-efficiency grass cover, fine and stable killing, fine grass grass, catching net, harvesting pass, spray and other post-emergence herbicides for controlling grass weeds, should not be used in gramineous plant lawns, such herbicides in control Undergraduate weeds can also harm the lawn.
3. Herbicides with long-lasting effects. Sulfonylurea herbicides such as chlorsulfuron, metsulfuron, benzsulfuron, pyrazosulfuron, acesulfuron, ethamsulfuron, nicosulfuron, etc.; imidazolinone herbicides such as chlorhexidine; Heterocyclic herbicides such as chlorpyrifos and chlorhexidine. 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. Herbicides that are toxic to the soil. Some herbicides of amides, ureas, and triazines and alachlor, acetochlor, humulus, sekzin, simazine, atrazine, chlorpyrifos, cotton grass and the like. 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 pentachlorophenolate 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. There are herbicides that drift and pollute. The drifting pollution problems of the herbaceous enemy, He Dazhuang, etc. are 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. Herbicide with odor. For example, the smell of 2 A 4 chlorine is irritating to humans. After inhalation, it has an effect on the stomach of the human body, and it also causes phytotoxicity to the seedlings and should not be used.
8. Killer herbicides. Such as glyphosate (Nongda), paraquat (g no trace) and so on. 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.
In short, in addition to the prevention of direct damage to the flower seedlings and lawns, the selection of herbicides should also prevent some potential, possible, hidden damages, so as not to cause the yield, quality and surrounding environment of flowers, seedlings and lawns. Unrecoverable damage. 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.
