Protection of your valuable crop is an important concern for all growers. Are you looking to “rescue” a grow that is rapidly going downhill? As the product’s name and the big red cross on the label art indicate, this is a plant health remedy supplement that is meant to address nutrient deficiencies that often cause such problems as “yellow plant syndrome.” Revive Crop Protection focuses on immediately restoring the green to your plants through proper chelation for nutrients to correct the yellowing. It’s good to go on mature plants and also on young rootlings or cuttings, and you can use it in foliar or root treatment application. The active ingredients are calcium nitrate and magnesium nitrate. The product is sold in 1L and 4L container sizes.
