First, simazine is also called simazine, the English common name is Simazine. Selectively inducing soil-borne soil treatment of herbicides. After the drug is absorbed by the weed roots, photosynthesis is inhibited and the weeds are killed. It is not toxic to plant roots and has no effect on seed germination. Only after the nutrients in the seeds are exhausted, the seedlings die. The weeds showed signs of suffering 7 days after the application. It can be used to control perennial weeds of annual weeds and seed reproduction. The efficacy of controlling broadleaf weeds in annual weeds is higher than that of grass weeds. Weeds have a good effect before they are unearthed and in the germination period. Orchards and woodland are mostly used during the peak period of spring field germination.
Note: The residual effect of simazine may have adverse effects on the growth of certain crops, especially when drought or rain is low or the dosage is high. Although it is still toxic to sensitive crops every other year, such as wheat, barley, cotton, soybean, cross Flower vegetables and so on. When the soil moisture is sufficient and the moisture is good, it is beneficial to exert the effect.
Second, the gram tracer is also known as paraquat, the grass is fast, the English common name Gramoxone, paraquat. Quick-acting contact-killing herbicide. The leaves began to suffer discoloration 2 to 3 hours after the leaves were treated. It has a rapid destructive effect on the green tissues of both monocots and dicots, but it cannot be transmitted. The gram can not penetrate the corked bark, and once the agent is in contact with the soil, the passivation fails and there is no residue. It can prevent a variety of weeds, and has the best effect on weeds in 1~2 years. It can only kill the green part of perennial weeds, but can't kill the underground part. The weeds are low in dosage and low in the adult period. Generally 667 square meters of 250 ~ 300 ml (20% of the trace), directed spray on the ground.
Precautions: When the temperature is high and the sun is sufficient, it is beneficial to the effect of the drug; the liquid mist can not be dripped into the green part (leaves, buds, etc.); the water contact has no effect on the efficacy within 30 minutes after the application.
Third, glyphosate is also known as Nongda, Zhencao Ning, English common name Glvp hour osate. Systematic, broad-spectrum, herbicide-killing herbicide. The green part of the plant absorbs well and is mainly absorbed by the leaves. After application, the agent was quickly transferred from the phloem and transferred to the underground roots and underground stems within 24 hours. The symptoms of plant poisoning were slow after application, and the annual weeds generally began to respond after 3 to 5 days, and all died after 15 days. The perennial weeds gradually became yellow after 3 to 7 days after application, and then browned. Lodging, the underground part is rotten. After 20~30 days, the above ground part is basically dry. It has a broad spectrum of herbicides, and some plants of Liliaceae and Leguminosae are highly resistant to this agent. For annual weeds, the dosage is 1.8~3 kg/ha. For perennial weeds, such as psyllium, the dosage is 1.25~1.5 kg/ha. For perennial malignant weeds, such as reeds, ice grass, etc., the dosage is 1.8~3 kg/ha. For the amount of water 300~450 kg, spray treatment should be carried out during the vigorous growth period of weeds.
Note: The liquid can not be touched or drifted to the green part of the fruit tree (leaves, buds, young shoots, etc.); it is sprayed with rain 6 to 8 hours after spraying. Ammonium sulfate and surfactant can activate the activity of glyphosate, and proper addition when spraying can enhance the herbicidal effect. Glyphosate water is corrosive to metals and should be used as much as possible in storage and use.
Four, 2, 4 - butyl butyl ester, also known as two or four drops of butyl ester, English common name 2, 4 - day butylate. A hormonal selective herbicide with strong systemic conductivity. It is mainly used for post-emergence stem and leaf treatment. When the liquid is sprayed on the leaf surface of the plant, it passes through the stratum corneum and cell membrane and is finally transmitted to various parts. It has good exhibitability, strong penetrability, easy to enter the plant body, is not easily washed away by rain, has a strong volatility, and the liquid droplets can drift far away in the air, causing sensitive plants to suffer. It is mainly used to control the weeds, scorpion, scorpion, sorghum, mustard, sage, bitter stalk, Xanthium, sinensis, and purslane. The broadleaf weeds are 3~5 leaf stage, the dosage is 0.43~0.54 kg/ha, and the water is added 300~400 kg, evenly sprayed.
Note: 2,4-butyl butyl ester is highly volatile, and it is easy to cause phytotoxicity to nearby sensitive crops during application. Spraying is stopped when the wind speed is 4 m/s or more; the device for spraying 2,4-dt-butyl ester is preferably used exclusively, and cannot be contacted with acid and alkaline substances.
Five, Mori grass net, also known as grass irrigation, Oster, English common name Sulfometuron-met hour yl. Selecting a systemic herbicide that allows plants to conduct up and down after absorption, but the effect is slow. The main mechanism of action is: through the absorption of roots and leaves of plants, inhibiting seed germination and seedling growth, making the plant shape dwarf, tissue chlorosis, yellowing, root aging, lateral roots and main roots become shorter, and the number of lateral roots is reduced, so that weeds lose competition. ability. The herbicide spectrum is broad and has certain selectivity. The coniferous tree has greater tolerance to it, and has better control effect on alfalfa, alfalfa, bluegrass, foxtail, ice grass, flat storage and licorice. It is mainly used to control weeds in coniferous forests and nurseries. Generally, 70% of Morigra 1500 g/ha is used, and 50 kg of water is used to spray stems and leaves.
Note: This medicine has poor control effect on grass weeds and has certain phytotoxicity to broadleaf forest nurseries. It should be used with caution.
