Esaprim Granules is a pre-emergence and postemergence herbicide that controls weeds from seed and weed seedlings. However, established perennial species, large annuals and large broadleaf weeds are not satisfactorily controlled at the rates recommended. It acts mainly through root absorption. And its effectiveness depends on the occurrence of control rainfall or irrigation to move it down into the weed zone. Moreover, duration and effectiveness of control depend on the amount of chemical applied, soil type, rainfall and particular weed species.
The limitation for the maximum rate of atrazine application in all crops except plantation forestry is to an amount of product equivalent to 3 kg ai atrazine/ha per year. DO NOT exceed this limit, especially when applying an atrazine herbicide post-emergence, where an atrazine herbicide has been applied preemergence. Additionally, the maximum rate of application in plantation forestry is an amount of product equivalent to 4.5 kg ai atrazine/ha per year in sandy soils and those defined as highly erodible, and product equivalent to 8 kg ai atrazine/ha per year in clay loam and heavier textured soils.
DO NOT mix, load or apply within 20 m of any well, sink hole or intermittent or perennial stream or river. Esaprim granules readily mix with water. Add required quantity to the spray vat with the tank filter mesh removed and the vat 50 to 75% full with water. The agitation system should be running during addition of the product and during the spraying operation. If left to settle, stir and re-suspend any settled material before starting pump and
spraying product. Also, avoid drawing accumulated particles into outlet pipe. DO NOT pre-mix in a bucket as a paste.
Wetting agent: Add Agral at 125 mL/100L or BS1000* Bio-Degradable Surfactant at 75 mL/100 L of spray
mixture when applying to emerged weeds as a foliar spray.
Incorporation (pre-plant and at sowing application)
This product acts mainly by root absorption. Its effectiveness depends on the occurrence of rainfall or irrigation to move it down into the weed root zone. Sufficient rain or irrigation to thoroughly wet the soil through the weed root zone should occur immediately after application to provide appropriate weed control. Delay in activation of the product may result in some weed growth. In flood or furrow irrigation situations, complete and continued activation of the product may not occur. This is due to a thin band of dry soil on the surface during or after irrigation. Mechanical incorporation after application, using light harrows to incorporate the product into the soil not more than 4 cm deep is required to ensure the irrigation
water activates the product.
Always apply the product to an even unridged seedbed.
