For mixing small amounts of herbicides, fungicides or insecticides, here are rough estimates: When recommendations call for a pound of wettable powder in 100 gallons of water, use 1 level tablespoon per gallon of water. Two pounds per 100 gallons equals 2 tablespoons per gallon. For each pint of liquid in 100 gallons of water, use one level teaspoon per gallon.
Plants such as roses, chrysanthemums, and others, which are subject to leafspot diseases, should already have had last year’s mulch and fallen leaves removed, and new mulch should have been applied. Use either sprays or dusts to control diseases. Insects such as thrips and aphids often are a problem on new growth.
