Description Dimethomorph 50 percent WP is a systemic and locally systemic fungicidal formulation used for the management of oomycete pathogens in vegetable and horticultural crops. It is particularly effective against downy mildew and late blight causing organisms. The product contains a cinnamic acid derivative that interferes with pathogen cell wall formation, which makes it a valuable tool in resistance management programs. Its wettable powder formulation dissolves smoothly in water and supports uniform coverage across dense foliage.   Mode of Action Dimethomorph penetrates leaf tissues and accumulates in growing regions where pathogens attempt to colonize. It disrupts the synthesis of cellulose in the cell walls of oomycetes, causing structural collapse of germ tubes and haustoria. This interruption stops fungal development during early infection stages and prevents the formation of new sporangiophores, giving the crop a strong protective shield.   Benefits • Delivers strong action against downy mildew and late blight • Prevents pathogen establishment by inhibiting cellulose biosynthesis • Ideal for integrating into resistance management programs • Supports healthy canopy growth through reliable protection • Ensures consistent performance under high humidity and disease pressure
