1. Rice Blast Disease
Rice blast is one of the most important rice diseases, can cause substantially reduction of output, if it's seriously, the reduction will be 40% to 50%, no harvest, which occurred all over the world.
The disease occurs in all over, mainly on leaf and section. It can cause varying degrees of reduction, especially neck blast will take place early and heavy, then no harvest.

Basic Information
Normally, output reduction 10%-20%, if it’s serious, will be 40%-50% even, no harvest. Mainly damage leaves, stems, fringe. According to the damaged period and injury parts are divided into seedling blast, leaf blast.
Symptoms
Seedling blast: occurs before clover in the way of the seed infection. Disease seedling gray base, the upper brown. Ifhumidity is high, disease would generate a lot of gray and black mildew layer.
Leaf blast: small, dark green spots appeared on leaves, gradually expanded to fusiform spots. Spots central is gray, brown edges, with pale yellow halo at outside.
Acute type of lesion: On leaves form a nearly round or oval, dark green spots. White spot lesion type: leaves after damaged, will produces small white nearly round spots, does not produce spores.

2. Rice Sheath Blight

Basic Information
Rice sheath blight is also called Rhizoctonia solani Kuhn, it’s one of the main diseases on the rice production.
Symptoms
The disease could be occur from seedling stage to ear sprouting stage. The damaged leaf sheath will generate dark green fuzzy spots and gradually expand oval. If very serious, a few of spots will be fused as big ones. Usually, lead to the leaves withered.Roots of leaves damaged will soon be rot and stalk is easy to fold. If neck of spike is damaged, often can’t head sprouting or the blighted grain will more after head sprouting. Finally, output will be reduced.
Transmission Route
Bacteria mainly in the way of sclerotium for overwintering in the soil can also be on the sick mycelium or field weeds and other host. In spring, the sclerotium will floating on water and mixed with other around adulterants. After transplant rice seedlings, sclerotium will adhere to the leaf sheath near water. And will germinate the hypha on the favorable condition and invade Leaf sheath tissue.

1. Chilo suppressalis
Chilo suppressali, Lepidoptera, Pyralidae. It is one of occurring frequently pests, output reduction 3% to 5%, if seriously, will redcution over 30%. Besides damage rice, also damage corn, sorghum, sugar cane, rapeseed, beans, wheat and reeds, other weeds.

Distribution and Damage
Mainly happens on hilly and mountain area. The distribution will be different as the different rice fileds. In the general single cropping area, occurrence is more serious, double cropping rice on plains, the occurrence is relatively light. Host plants are rice, wild turbot white, sugar cane, sorghum, maize, wheat, millet, barnyard, beans, rape, grass etc.
Morphological Characteristics
Chilo suppressali is the strong rival for rice, it also feeds cruciferous vegetables and a variety of weeds. Larvae eats the stem, causing dead heart. Male imagoes wingspan about 20 mm, female 25 to 28 mm. Pale gray-brown head, round, top sharp. Chest and wing base white to gray and brownish. Forewing yellowish to dark brown, white hind wings, near the outer edge of the wings slightly brown. Female body color is paler than the male.
Solutions

2. Tryporyza incertulas

Basic Information
Tryporyza incertulas belongs to lepidoptera, pyralidae.
Morphological Characteristics
Body length of 9 ~ 13 mm, wings 23 mm to 28 mm. The female proala is nearly triangular, yellowish white, male proala is pale grayish brown with a small black spots in the center.
Egg: Long oval shaped, egg covered with brown tomentum, like a half moldy soybean.
Larvae: ash black at hatch, length 14 ~ 21 mm after mature, light brown head, yellowish green or yellow white body.
Pupa: Yellow green. Before the eclosion, the gold yellow is female and silver is male.
Symptoms
Tryporyza incertulas only damage rice, it’s a monophagous pest. The larvae bore into rice plants, eat the leaf sheath tissue, ear bracts and rice stem. Then causing the dead heart seedlings, dead booting, white head etc, serious influence on rice production.The two stages: tillering stage and booting stage are called ” Dangerous growth period”.

3. Rice leaf folder

Basic Information
Rice leaf folder belongs to lepidoptera, pyralidae. Widely distributes in most paddy rice region. It's a kind of migratory pests. Imagoes are phototaxis and will spawn more eggs in the suitable temperature with high humidity. Generally, every female can spawn 40 ~ 70 pieces.
Morphological Characteristics
Imago: 7 to 9 mm long, light brown, the proala of male with the flash "eye spot", the proala of female without "eye spot".
Egg: ash black at hatch, length 14 ~ 21 mm after mature, light brown head, yellowish green or yellow white body.
Larvae: Yellow green. Before the eclosion, the gold yellow is female and silver is male.
Pupa: 7 ~ 10 mm long, cylindrical. Color changed from yellow to brown.
Symptoms
Besides rice, it damages barley, wheat, sugar cane, millet, etc. Larvae damage rice, hiding in leaves for eating their epidermis and mesophyll, leaving only the white lower epidermis. It will affect the regular growth or even wither if rice seedling stage damaged, and if damaged during the tillering stage to elongation stage, will cause tillers decreased, plants shortened and growth period delayed.After booting, specially from heading period to full heading stage,once boot leaves damaged, it will affect flowering and fruiting, rate of blighted grain is increasing , finally the yield will decrease.

4. Rice planthopper

Basic Information
Rice planthopper is a pet that belongs to insecta, homoptera and delphacidae. It damages to rice and other crops by sucking plant sap. Mainly divided into three kinds: Brown planthopper (Nilaparvata lugens), White-backed planthopper (Sogatella furcifera) and Laodelphax striatellus. White-backed planthopper is the main pest for early- season rice at the earlier stage. Brown planthopper will be the main pest at later stage.
The major rice planthopper for middle-season and late -season rice is laodelphax striatellus. It seldom directly caused disaster but can spread the virus of rice, wheat, corn etc.
Morphological Characteristics
Small size, short and cone-shaped tentacle, transparent wings, often have two types long-winged and short-winged.
Symptoms
The damages caused by Rice planthopper for rice showed two aspects. By sucking rice‘s sap to prevent growth, if seriously, rice will be withered into blocks. Spawning also stabbed plants, destroy conducting tissue, spread the virus disease and prevent nutrients transportation.
