A liquid formulation that can protect crops from too much heat of the sun was recently showcased in a demo farm put up by Sinochem Philippines at the UP Los Baños campus in Laguna.
The product is called Purshade which has been registered with the Fertilizer and Pesticide Authority (FPA) for use in pineapple, banana and corn. When sprayed on the leaves of the said crops, it forms a film that protects the plants from the harmful effects of excessive ultraviolet and infra-red radiation. Too much radiation can cause scalding in fruits and leaves resulting in poor quality harvests.
Aside from protecting the plants from too much radiation, Purshade also boosts plant growth because it contains calcium that is needed for improved quality of harvests.
