Abstract
The invention discloses a propineb and azoxystrobin-containing antiseptic composition, which comprises propineb and azoxystrobin in mass percent ratio of 5-80:40-1 and can be made into a wettable powder, water dispersible granules or a suspending agent. The compound antiseptic composition can be used for preventing and controlling diseases of fruit trees and vegetables, particularly tomato early blight, cucumber downy mildew, altemaria mali Roberts and sigatoka.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of bactericidal composition that contains Propineb and azoxystrobin compound with synergistic effect.
Technical background
Propineb (propineb) belongs to dithiocarbamate fungicide, and pure product are the white powder of special odor slightly.Stable under drying condition, under moist, acid, alkali condition, decompose.Molecular formula: (C
