The tests in the field also indicated that the above mixture was perfect on the control of powder mildew. The effect of the mixture was 98.4 to 71.5% against powdery mildew of cucumber at 10-40 mg/l. The results showed that the mixtures in 1:10 had obvious synergistic interaction, and it can postpone fungicide resistance.
