Butachlor (Machate, Mesochlor, Benzachlor)

1. Characteristics of action: Butachlor is an amide selective pre-emergence herbicide. It is a selective pre-emergence herbicide with systemic conduction. It is absorbed through young shoots and roots and inhibits protein synthesis inside weeds, thereby killing weeds. Butachlor is effective against pre-emergent and pre-second-leaf weeds. The original drug is a light yellow oily liquid with a slightly aromatic smell. It is non-volatile at room temperature and has good photolysis resistance. The leaching depth in the soil does not exceed 1 to 2 cm. It is degraded by microorganisms in soil or water and lasts about 100 days. More than 90% of the active ingredients can be degraded, so there will be no impact on subsequent crops. Low toxicity to humans and animals. Slightly irritating to human skin and eyes. Highly toxic to fish and aquatic life.

2． Preparation: 50%, 60% emulsifiable concentrate, 5% granules.

3． Control objects and usage techniques Butachlor is used to control grass weeds, some sedge weeds and some broadleaf weeds; such as barnyard grass, crabgrass, sedge, stephanotis, sedge, and special-shaped weeds. Sedge, water amaranth, jiejiecai, moshangcai. To control weeds in melon fields, pesticides can be applied before emergence or 1 to 2 days before transplanting. Use 900 to 1,500 ml of 60% EC per hectare, add 750 kg of water, spray, and then cover with film.

4. Notes: ① Butachlor is effective against grass weeds before the second-leaf stage, but has poor control effect on chickweed. ② This agent is flammable and cannot be stored at high temperatures or with open flames. ③ It is irritating to eyes and skin, so please pay attention to protection.

(1) 2,4-D butylate [English common name] 2,4-D butylate 5rSth.amp;

[Chemical name] 2,4-Dichlorophenoxyacetic acid n-butyl ester It is a herbicide with strong systemic conductivity. It is mainly used for post-emergence stem and leaf treatment in wheat fields. After the liquid is sprayed on the surface of weed stems and leaves, it passes through the cuticle and cytoplasmic membrane and is finally transmitted to all parts of the plant. Partly. After the weeds are affected, the stems and leaves will become twisted and deformed, and eventually die. Broad-leaf weeds will generally have deformed and curled symptoms 24 hours after application, and will die in 7-15 days. 1j-i nj`

Due to the differences in external morphology, tissue structure and physiology between plants, they show different resistance to 2,4-D. Generally, dicot plants degrade 2,4-D. The speed of 2,4-D is slow, so the resistance is weak and it is easy to be damaged. Gramineae can metabolize 2,4-D quickly and make it inactive. Therefore, this drug has an advantage between grasses, wheat and dicotyledonous weeds. Very good selectivity. Igt; zn$d*0

[Preparation] The commonly used preparation is 72% 2,4-D butyl ester. EC"qp_*Y

[Application technology] 72% 2,4-D butyl EC is used in wheat fields to control artemisia, shepherd's purse, pigweed, polygonum, pigweed, rhizome, and bittern. Broad-leaf weeds such as amaranth, spinach, and field bindweed are ineffective against gramineous weeds. Suitable application period and dosage: Use 72% 2,4-D butyl EC 40- per acre during the greening stage of wheat. 50 ml, add 25-30 kg of water and spray evenly. 2,4-D butyl emulsifiable concentrate can be mixed with methamphetamine, bromoxynil, etc., and the dosage should be reduced by half to expand the herbicidal spectrum. Pay attention to: 1.2, 4. -D butyl ester is highly volatile, and the spray droplets can drift far in the air, causing damage to sensitive plants. Spinach, beans, cotton, rape, sunflower and other dicotyledonous crops that grow at the same time as cereal crops are harmful to them. It is very sensitive and is one of the main causes of phytotoxicity in broad-leaf crops in my country. Therefore, the pesticide should be applied in windless or light weather. It is best to wear a protective cover on the nozzle of the sprayer to prevent the spray droplets from drifting to dicotyledonous crops. This drug cannot be used in wheat fields interplanted with sensitive crops. 2. Strictly control the application time and dosage. Wheat is sensitive to 2,4-D butyl ester before the third leaf and after jointing. Application at this time is easy. Cause phytotoxicity in wheat.

Symptoms of phytotoxicity appear only after the heading stage of wheat. In mild cases, when wheat heads, the ears are bent and difficult to pull out from the flag leaf, showing a "crane's head" shape. In severe cases, the wheat ears appear deformed and become "square-headed" ears. Therefore, the drug should be applied after the 3-leaf stage of wheat and before jointing. 3. The equipment for packaging and spraying 2,4-D butyl ester must be specially used to avoid "secondary pollution". 4.2, 4-D butyl ester EC should not be in contact with acidic and alkaline substances to avoid reduction in efficacy due to hydrolysis, and it should not be stored together with seeds and chemical fertilizers. |nN'-el

[ Chemical name] 2', 6'-difluoro-5-methyl (1, 2, 4) triazolo (1, 5-a) pyrimidine-2-sulfonyl anilide PwU}lt; Hrl]

[Characteristics] Saflufenacil is a sulfonamide systemic herbicide. It is absorbed by the roots and leaves of weeds, transmitted through the xylem and phloem, accumulates in the plant meristem, and inhibits acetolactate in the plant. Synthetic enzymes stop the biosynthesis of branched-chain amino acids - leucine, valine, and isoleucine, hindering protein synthesis, stagnating plant growth, and eventually leading to death. It is a relatively slow process until the plant body dies. The typical symptoms after weeds absorb saflufenacil are: the midrib of the leaves becomes green, the veins and tips of the leaves turn brown, and the heart leaves begin to turn yellow and purple, and the internodes become shorter. , the terminal bud dies, and eventually the whole plant dies. The selectivity of saflufenacil between crops and weeds is due to the fact that after the resistant crop wheat absorbs saflufenacil, it rapidly undergoes degradation and metabolism, causing the activity of saflufenacil to be lost, thereby ensuring the safety of the crop; In sensitive weeds, this metabolism is very slow, killing the weeds without harming the crop.

When mixed with other herbicides, first add 1/4 water to the sprayer, then add broadgrass clear mother liquor, then add other herbicides and mix evenly. 3. When treating stems and leaves of broad grass clearing, spray pesticides on sunny days when the temperature and humidity are suitable. Under drought and cold conditions, the herbicidal effect of this drug will decrease. Adding vegetable oil and non-ionic surfactants during application can improve its herbicidal effect. 3Q*K (`{
