WELGRO® ZINC is a chemically stable product with a long shelf life that is not affected by light exposure. Is effective even in very acidic or calcareous soils, ensuring a reliable supply of zinc in any soil type. Being derived from a natural sugar (glucose), WELGRO® ZINC quickly enters the plant's metabolism through foliar or root applications (drip irrigation or injection). The first effects can be observed within 10 to 12 days after application. WELGRO® ZINC is a safe product that does not cause any phytotoxicity issues in treated crops, whether applied foliar or through root methods (injection or drip irrigation). The persistence of WELGRO® ZINC's action depends on various factors, such as the degree of deficiency, method of application (foliar, injection, or drip irrigation), dosage, rainfall, and more.
