Ametryn 80% WP
Ametryn 80% WP is a triazine selective systemic herbicide formulated as a wettable powder. Its technical material is white powder, which can be quickly diluted with water to form a uniform and stable liquid suspension. It sprays smoothly without nozzle clogging and is compatible with all types of agricultural spraying equipment. With low toxicity and eco-friendly properties, it is the dominant herbicide widely used in major sugarcane and pineapple planting regions.
1. Core Product Advantages
It works by inhibiting photosynthesis in weeds. The liquid agent is rapidly absorbed through weed roots and foliage before translocating throughout the entire plant, delivering dual effects of pre-emergence soil sealing and post-emergence foliar contact killing. Spraying after sowing suppresses weed seed germination; targeted spraying at the 2–4 leaf stage of weeds quickly eliminates young seedlings. It offers a long residual period and drastically cuts labor costs from repeated applications. Its broad weed control spectrum covers most annual grasses and broadleaf weeds including crabgrass, barnyard grass, black nightshade, billygoat weed and oxalis, and also provides remarkable suppression on shallow-rooted perennial weeds.
Containing 80% high-purity technical material, it features low impurity content and low application rate per unit, delivering far better cost performance than low-concentration formulations. Premium wetting and dispersing agents are incorporated into the formula. Once mixed with water, it disperses instantly into fine liquid suspension with high suspension rate. Minor sediment after long standing can be fully rehomogenized by stirring. The spray droplets adhere evenly to target surfaces and resist rain wash-off. Boasting outstanding crop selectivity, it is highly safe for sugarcane and pineapple under standard directed application, with no adverse impact on rhizome development or final yield. It degrades mildly in soil with low residual levels and poses no phytotoxicity risks to subsequent rotational crops.
2. Application Scope
It is primarily registered for sugarcane and pineapple, and can be applied as directed inter-row spray for citrus, corn and potato crops. For sugarcane fields, apply 130–200 grams of formulation per mu diluted with 30–40 kg water for uniform spraying. For pineapple fields, use 120–180 grams per mu while avoiding tender shoots and new leaves of crops. Optimal control efficacy is achieved when weeds are at the seedling stage, and moist soil conditions can further accelerate weed killing.
3. Precautions
Avoid application on windy days, at midday high temperatures or before rainfall. Re-spray is required if rain falls within two hours after treatment. Strictly adopt directed spraying to prevent liquid drift onto sensitive crops such as vegetables and young seedlings. Applicators must wear full protective gear during operation and refrain from eating, drinking or smoking. Seal and store the product in cool, dry places away from water sources, children and livestock; never store alongside food or feed. Dedicated spraying equipment is recommended, which must be thoroughly cleaned after use to avoid residual contamination on subsequent crops.
In summary, Ametryn 80% WP forms stable liquid mixture with easy operation after water dilution. Integrating pre-emergence suppression and post-emergence killing with broad-spectrum and long-lasting efficacy, it balances farmers’ input costs and crop safety. Suitable for long-term use by individual growers and large-scale commercial plantations alike, it stands as the preferred diluted liquid herbicide for weed control in tropical cash crop fields.
