Herbicides that make flowers and seedlings "scared"

There are many herbicides that should not be used in gardens, flower nurseries and lawns. The introduction is as follows:

The post-emergence herbicides for the control of broad-leaved weeds, such as 2A, 4C, 2,4-D, Benzonsone, Baicao, Entrepreneur, Huwei, Keziling, Haoshida, etc., must not be used in nurseries, gardens, and horseshoe gold. Lawn application.

Effective post-emergence herbicides for control of grassy weeds, such as efficient herbicides, stable and stable killers, fine grasses, glyphosate, confedophanes, and galites, etc., to prevent herbicides from grasses and weeds should not be used in grasses. Used on lawns, such herbicides can also harm lawns while controlling grass weeds.

Herbicide sulfonylurea herbicides with long pot life, such as chlorsulfuron, metsulfuron, benzulfuron, pyrazosulfuron, tosulfuron, ethametsulfuron, sulfenon, etc.; oxazolinones Herbicides such as puproxate, etc.; heterocyclic herbicides such as fast killing crickets, chlorproterone and the like. These herbicides have a long duration in the soil. In nurseries where these herbicides are used, flowers and seedlings planted three years later may be harmed, and seeding grass after three years may be harmed. Metsulfuron will cause the tall fescue to not sprout, and if it is sprayed on the tall fescue lawn, it will cause yellow feces and death. Guangmianling can cause bleaching of turfgrass plants.

Herbicide amides, urea, herbicides of benzotriazoles, and acetochlor, acetochlor, fluometuron, saikojin, simazine, atrazine Grass net, cotton grass and so on. If these herbicides are applied on the lawn, they will affect the root system of the turfgrass in the presence of accumulated water, and will affect the development of the turfgrass; where it is continuously applied, it will cause deterioration and compaction of the soil structure and affect the soil around the turfgrass roots. Ventilation, which in turn causes turf plants to yellow.

The highly toxic or carcinogenic herbicides sodium pentachlorophenol and paraquat are very toxic and are absolutely prohibited in nurseries and lawns. The herbicide ether has been banned in many countries due to carcinogenicity, and our country has been banned since 2000. Lasso is carcinogenic to animals and should not be used. Trifluralin has been banned in Europe due to carcinogenicity.

The problem of pollution caused by the drifting herbicides such as the paraquat enemy and the Da Zhuang, etc., is relatively large. Generally, there are flowers and seedlings around the lawn. Spraying herbicides such as paraquat and glutinous rice on lawns can easily affect the growth of surrounding flower seedlings.

The odor of herbicides such as 2 A 4 chlorine has an irritating effect on humans. After inhaling it, it will affect the human stomach, and it will also cause phytotoxicity to seedlings. It should not be used in nurseries and lawns. Substitution of urea herbicides such as chlorotoluron, isopropenol, etc., which have odor, and are herbicides that absorb the conductivity, will reduce the quality of seedlings and flowers and should not be used.

Inactivated herbicides such as glyphosate (Rongda), paraquat (graceless), etc. Although some seedlings have a certain tolerance to low-dose glyphosate, sometimes glyphosate damage to seedlings is difficult to judge intuitively, and sometimes this kind of injury is slow, and when sprayed with glyphosate, it is inevitable. If there is drift, it will cause damage to sensitive flower seedlings around.

In short, when selecting herbicides, in addition to considering the prevention of direct damage to the flower nursery stock lawn, it is also necessary to prevent some potential, possible and hidden damages, so as not to affect the yield, quality and surrounding of flowers, seedlings and lawns. The environment causes irreparable damage. In use, care should be taken to select herbicides with broad spectrum of herbicide, moderate efficacy, good eradication effect and no pollution according to different needs, varieties, and periods.
