Ametryn (834-12-8) technology
1. In sugarcane fields, 130 to 200 grams of 80% atramethrin (104 to 160 grams of active ingredient) should be used per acre after sowing and before emergence of sugarcane. If the soil is heavy and sticky, use a high dosage; if the soil is loose, use a low dosage. The spray volume is 40 to 60 liters per mu. Post-emergence Ametrynis at the 3-4 leaf stage of sugarcane. The best Ametrynperiod is when most weeds are out and the weeds are 10 to 20 centimeters tall. The spray volume is 30 to 50 liters per mu. Although Ametryn is safe for sugarcane with more than 4 leaves, direct spraying should be avoided as much as possible. Aim the post-emergence spray nozzle at the ridge and furrow, and lower the nozzle for directional spraying. In sugarcane fields where barnyard grass, stephanotis, red thistle, field bindweed, spinach and bermudagrass cause serious damage, it is best to use pre-emergence spraying. Mixing Ametryn with dichloride or 2-methyl-4-chloride can expand the herbicidal spectrum and improve the efficacy. Use 70 to 80 grams of Ametryn per acre (active ingredient 56 to 64 grams) plus 80% diclofenac 70 ~80g (active ingredient 56~64g), or 56% 2-methyl-4-chloride 50g (active ingredient 28g). When applying pesticides after emergence, adding 0.5% surfactant to the liquid is beneficial to the effectiveness of the drug.
2. In pineapple fields, pre-emergent pesticides should be used on weeds after harvesting or before planting. Use 130-260 grams of 80% Ametryn wettable powder per acre (104-208 grams of active ingredient), add 30-50 liters of water and spray.
If sprayed once every 1 to 2 months, the dosage is 1/4 or 1/2 of the conventional amount (260 grams/acre). Directional spraying can keep the field free of weeds.
3. In banana fields, apply pesticides before and after seedlings when transplanting or at other times. Use 75 to 330 grams of 80% Ametryn wettable powder per acre (60 to 264 grams of active ingredient), and add 30 to 50 liters of water to spray. The interval between repeated applications is 3 to 4 months. The maximum pesticide Ametrynrate in a year is 1.7 kilograms per mu (1360 grams of active ingredient).
4. Potato fields Atramethrin can be used as a desiccant on mature potato vines. Generally, 70 to 150 grams of 80% Ametryn wettable powder (56 to 120 grams of active ingredient) and 66 liters of spray liquid are used per mu. Be careful and thoughtful when spraying. Drying time is 10 to 14 days. Drying time required increases at low temperatures. At the same time, it can also control weeds in the seedling stage in the field.
The liquid preparation adopts the secondary dilution method. First pour the required amount of medicine into the container, add a small amount of water and stir it into a paste. Slowly pour the paste into a medicine box containing a certain amount of water, stirring while pouring, and then add water to the required amount.

Herbicide Ametryn Preparation 80% Ametryn Wettable Powder
Characteristics of action: Atramethrin is absorbed through plant roots, stems and leaves. Spraying the medicinal solution onto the plants and being quickly absorbed by the leaves can prevent the stems and leaves from being wetted by rain after Ametrynand reducing the efficacy of the medicinal product. After the plant absorbs Ametryn, it is conducted upward and concentrated in the plant apical meristem, inhibiting electron transfer in photosynthesis of sensitive plants, leading to the accumulation of nitrite in the leaves, achieving the purpose of weeding. Non-sensitive plants can degrade Ametryn. Validity period is about 40 days.
Suitable for crops such as corn, sugar cane, pineapple, banana, cotton, citrus, etc.
The difference between Ametryn (834-12-8) and Atrazine
Ametryn: selective systemic herbicide. It kills herbicides quickly and is a typical photosynthesis inhibitor. By inhibiting photosynthetic electron transfer, nitrite accumulates in the leaves, causing plant damage and death; its selectivity is related to differences in plant ecology and biochemical reactions, and it is best for the control of newly germinated weeds. It can be adsorbed by 0-5 cm of soil to form a drug layer, so that when weeds germinate and come into contact with the drug, Ametryn can promote plant growth at low concentrations, that is, it stimulates the growth of young shoots and roots, and promotes the increase of leaf area. Thickening of stems, etc.; at high concentrations, it has a strong inhibitory effect on plants. Atramethrin is suitable for controlling annual weeds in sugar cane, citrus, corn, soybean, potato, pea, and carrot fields. High doses can control certain perennial weeds and also control aquatic weeds.
Atrazine: It is a selective systemic pre-emergence and post-emergence herbicide. Mainly absorbed by roots, very little is absorbed by stems and leaves. It is quickly transmitted to plant meristems and leaves, interfering with photosynthesis and killing weeds. In resistant crops such as corn, it is decomposed by zeinase into non-toxic substances, so it is safe for crops. Herbicidal effect and selectivity: Similar to simazine, it is easily leached by rainwater to deeper layers, causing it to inhibit some deep-rooted weeds. It can be decomposed by microorganisms in the soil, and the residual effect period can be as long as about half a year, depending on the dosage, soil texture and other factors.
