Kind.Brassicaceous vegetable is usually easily endangered in planting process by germ, and soft rot is the common disease of one of which
Evil.Soft rot is as caused by soft rotten erwinia, belongs to bacterial disease, germ is depending mainly on same diseased plant and invalid body in soil
Survived the winter in earth, compost, clamp or strain of reserving seed for planting, splash, invaded from plant wound, in wound or iuntercellular by irrigation water and wind and rain punching
Nutrition is absorbed, secretion pectase decomposes the mesoglea of host cell, makes host cell discrete.Due to germ, host is extensive, can be
Lived away from home in soil accumulation, thus can from spring to autumn, breeding, constantly harm are infected on the various vegetables in field.
Cucumber bacterial angular leaf spot is one of important disease on cucumber.Generation is often mixed with cucumber downy mildew in field,
Scab relatively, is sometimes prone to obscure, but cucumber downy mildew early stage produces several water stain shapes of polygonal in vacuum side of blade
Scab, and bacterial angular leaf spot produces the water stain shape scab of needle-like in vacuum side of blade, often tens scabs occur simultaneously.Seedling and
Adult plant can be aggrieved, but with Adult plant blade it is aggrieved based on.Main harm blade, petiole, tendril and fruit, also infect sometimes
Stem.Cotyledon is fallen ill, and is just dried up in water soaking mode subcircular depression spot, rear micro-strip yellowish-brown；Adult plant blade is fallen ill, and is just emerald green
Water soaking mode spot, gradual change is filbert, and it is in polygonal that scab is limited by vein, grey brown or yellowish-brown, and blade back overflows milky white during high humidity
