• Application

  (1) Scope of application: Orchards, vegetable gardens, no-till land and non-arable land. DT50 in soil lasts 20-30 days, with 80% degrading within 30-45 days.
  (2) Target weeds: Mainly used on non-arable land to control annual and some perennial grass weeds and some broadleaf weeds such as shepherd's purse, cleavers, sedge, chickweed, bok choy, ice grass, wild oats, lambsquarters, sedge, barnyard grass, Kentucky bluegrass, purslane, foxtail grass, plantain, wormwood, field bindweed, horsetail, etc.
  (3) Application technology: Diamylphosphonate loses its activity upon entering the soil and is only suitable for foliar treatment. Its weeding effect is faster than glyphosate but slower than paraquat. It is easily metabolized and biodegraded, therefore it is safe to use. Half-life: 20-30 days. It is mainly used for weed control between rows in orchards and vegetable gardens, with a dosage of 1000~3000 g(ai)/hm2. For controlling annual weeds in apple, citrus, and vineyards, the dosage of 32% SL is 5~7.5 L/hm2; for controlling perennial weeds, the dosage is 7.5~10 L/hm2; and for controlling annual weeds in vegetable fields, the dosage is 3~5 L/hm2.;
