Abstract
With a field experiment the effect of fungicides on control of flax powdery mildew and on the yield and economic traits of flax were studied.The results showed that the effects of 32% MZ·myclobutanil WP 288g a.i./hm2 and 40% Lucky Star EC 24 mL a.i./hm2 could reached 50.0% and 47.78% respectively 20 days after application.The yields increased by 36.61% and 41.30% respectively compared with that of the control with only water.
