The key that orange lasts is to prevent decay, the germ of sodden fruit is in disease, and green mildew and green mildew are two kinds of disease with the most serious harm in lasting, occupy the 90 ％ of 70 ％ ～ that total sodden fruit leads about.
The key that orange lasts is to prevent decay, the germ of sodden fruit is in disease, and green mildew and green mildew are two kinds of disease with the most serious harm in lasting, occupy the 90 ％ of 70 ％ ～ that total sodden fruit leads about. Especially the wide skin orange such as lukewarm city mandarin orange kind happen more general.
Green mildew, green mildew belongs to fungus sex disease. Can make fructification bate, produce mold of cloth with soft nap of of all kinds, fructification is cankered, come on earlier two kinds of ill symptoms are same, namely shape of be soiled of water of ecru, circle, ill spot, ill ministry bate is easier crumple, after this expands quickly grow white mycelial, subsequently in the center of grow minute of unripe spore very quickly, indicate the different point of two disease from now on, cent gives birth to spore clump to be cyan, mycelial of predestined relationship white is encircled outside very narrow, have 1-3 millimeter only, cankered fruit won't the mildew is blueness with adjacent fruit adhesion; And green mildew is the predestined relationship outside green, white mycelial annulus is wider, cankered fruit Yi Yulin is close fruit photograph adhesion.

Old since, each district uses blueness of orange of prevention and cure of the spirit yield bacterium, ferry that hold cloth in the palm, green mildew more, dip fruit handles chroma to be much bacterium clever 250~1000ppm, the ferry that hold cloth in the palm is 500~1000ppm, add 100~200ppm2 at the same time, 4-D, because be used for a long time, discover the ferry that hold cloth in the palm, much bacterium is clever in recent years wait for benzene and Mi Zun kind produce resistance to the action of a drug to green, green mildew.
Some closer year come, green mildew of times Fu Lang prevention and cure mixes the antiseptic that Japan studies to develop green mildew, effect excel much bacterium holds cloth ferry in the palm cleverly. The experiment makes clear, hold cloth ferry in the palm with 70 ％ 1000 doubly 200ppm2, 4-D dip fruit, store up 100 days to prevent ill effect to have ％ of 7.8 ％ ~53.6 only; And use 25 ％ agent of times Fu Lang water 2000 ～ fruit of 3000 times dip, the effect that prevent disease achieves ％ of 82.5 ％ ~88.7, store up 100 days, good fruit rate amounts to 90 ％ above, and fructification is spent colourfully exceed groovy drug apparently.
Spore of green to controlling orange mildew, green mildew forms curb mildew Zun the effectiveness of the respect, bigger than holding the commonly used antiseptic such as cloth ferry in the palm, and the blueness that can restrain pair of ferry that hold cloth in the palm to wait for kind of drug to have resistance to the action of a drug, green mould is, but invalid to the other bacteria that cause disease. The chroma that fruit of the dip after collecting handles is 1000ppm, the chroma of 2000 ～ 3000ppm can be used in candle processing, green to preventing and cure, green mildew has specially good effect. According to the report: With ginger of bitter fine of Chinese herbal medicine, wild Ai Xie, mother chrysanthemum 8 ％ solution is washed if really, also have distinct effect to restraining this two bacterias. Benzene rice also is used extensively at controlling green, green mildew and disease of corrupt of the base of a fruit especially, commonly used the form of a drug is 50 ％ but wet sex powder, dip fruit use chroma is 250 ～ 1000ppm.
In store up in the process, send those who have green, green mildew to want to be collected in time, and the fruit near ill fruit wants with 1000ppm dip of the ferry that hold cloth in the palm is washed, box wall of pollution also should be cleaned clean with the ferry that hold cloth in the palm.
