Spray program for the big rose garden

This is a preventative program designed to combat most of the pests that commonly occur on roses. The chemicals used to compile this program have proved to be compatible with each other and safe (for the plant) within reason if used in the right sequence and at our recommended dosage rates. However, other factors may influence the effect the chemicals have on the plants, i.e. spray water, climate, soil, nutrient status, age of chemicals and storage conditions – spray technique is also critical. We have recommended certain brand names, we do not take responsibility if “generics’ are substituted. There are vast differences in the quality of chemicals with the same active ingredient, but of different origin (manufacture).

This program is based on the assumption that the amount of spray mix applied is approximately 800 to 1200 liter per hectare.

The program consists of a 2 week cycle (preventative) and several ‘special mixes’ that are only sprayed if necessary when an ‘outbreak’ has occurred or when weather conditions are favourable for the development of the pest or disease.

The following preventative spray program will control the following pests and diseases: – aphids, worms, rose beetles, thrips, scale, rose borer, spider mite, powdery mildew, black spot and rust.
