Wheat Disease Treatment
1. Wheat Powdery Mildew
Powdery mildew is a worldwide disease of wheat, the disease can encroach above ground organs of wheat, mainly leaves and leaf sheaths.
Stage Characteristics:
1. The early symptoms of wheat powdery mildew on leaves.
Early onset, leaf emergence 1 ~ 2mm white moldy, then gradually expanded to nearly round to oval white mildew, powdery mildew surface layer, the powder immediately fly in case of force or vibration.
2. The powder is a fungus mycelium and conidia. Later, the diseased portion mold layer becomes gray to light brown spots scattered on a pinhead-sized black grains point, that the pathogen cleistothecia.
Transmission route:
1. Bacteria can be conidiophore or ascospore and s spread by means of air flow to the susceptible wheat leaves. If temperature and humidity conditions are right, the bacteria grow germ tube which front enlargement formation appressorium, penetrate leaf cuticle, invade epidermal cells, the formation of haustoria. And mycelium will grow in vitro host, then conidiophores produce conidia, mature off, spread with air flow, repeated infection. Germs in the later stages of sexual reproduction, cleistothecia will be formed in the flora.
2. The Germs on the conidia stage can get over the summer by Disseminated reproduction on wheat seedlings which is in areas of low te-mperatures, also through cleistothecia on plant debris in the dry and cold conditions summering. Bacteria overwinter in two ways, one is conidium form, or by lurking in the tissues of the host mycelium.

The late long black, long and narrow shape, ambush in subepidermal strip pock, namely the telia.
2. Wheat leaf rust: Early onset appear chlorotic spots, reddish dye that emerged after the blisters (uredinium). Uredinium small, orange-brown, irregularly scattered on the leaves. Late in the back of leaf and stem grow on black broadly elliptic to oblong, buried under the epidermis in winter spores heap, it has a longitudinal tendency according to straw.
3. Wheat stem rust: Mainly harm the stalk, leaf sheath, lamina and fringe. Urediospore pile is bigger, long elliptic to strip, reddish brown, Irregularly scattered, formed a large spot. They penetrate the leaf. Later, there will grow blister teliospore heap with long and narrow shape in the sick place.
