Spraying is required at the beginning of the season, before budding, with regular application every 7 to 10 days--7 days if there is rain and 10 if the conditions are dry.

Plants make their own food out of inorganic compounds through a process called photosynthesis that takes place in the leaves. The ingredients necessary for photosynthesis are light, water and carbon dioxide.
Plants are called producers. This is because they produce their own food! They do this by using light energy from the Sun, carbon dioxide from the air and water from the soil to produce food-in the form of glucouse/sugar.
