On April 19, a cultivates strawberry friend that comes from battalion mouth city is in farming chamberlain interlocution area quizs, how does strawberry grow to should prevent and cure so? Look how to return a responsibility together:
Beginning is to carry ill spot of shape of the be soiled that show water on the head if really, development becomes Brown disease spot after, ill fruit is wet when humidity is big soft decay. The disease when air is dry submits dry corrupt form if really, fall off into fructification in advance.
Will look farming how does chamberlain expert diagnose:
Mao Weishan (the plant protection technology that Yunnan saves autonomous prefecture of Dali the Bai nationality to be good at orange, grape, pomegranate, jujube)
Gray mold harm, with Niao of 50% different bacterium 1000 times fluid, 0 · 3% Ding Zixiang phenol 600 to 800 times fluid, 50% much mildew are clever 1000 to 1500 times fluid, mi mildew amine, amine of Mi bacterium annulus, second mildew power, amine of Ding acyl bacterium, wooden mould, corrupt mildew benefit prevents and cure. The attention accuses lukewarm accuse wet.
Lu Pi yuan (city of Henan province Zhengzhou is good at plant protection technology)
Consider gray mold disease, bacterium nucleus disease is endangered, picked directly, can use corrupt mildew profit, different bacterium Niao, or amine of Ding acyl bacterium, or amine of Mi bacterium annulus, or Mi mildew amine prevents and cure, use drug alternately, notice ventilated take a breath.
Liu Feng is spent (the plant protection technology that Shandong saves He lustre city to be good at the crop such as Chinese cabbage, strawberry, green, soja)
Gray mold, with corrupt mildew benefit, niao of bacterium of different of amine of mildew of Mi of amine of Ding acyl bacterium prevents and cure.
Feng Tao (the Anhui province 6 install city to be good at plant protection technology)
Gray mold harm, amine of use Mi mildew or different bacterium Niao or corrupt mildew benefit or amine of Ding acyl bacterium or bacterium nucleus prevent and cure completely.
Farming chamberlain knowledge small classroom -- strawberry gray mold
Endanger a symptom:
Basically spend to kill implement, handle of fructification, lamina, fruit.
One, flower implement the calyx when coming on shows the blob with big pinprick of shape of water be soiled, expand after intimate circle or irregular form ill spot, gradually outspread reach young fruit to ovary, young fruit forms ill spot of shape of water be soiled finally, when moisture rapid soft corrupt, produce layer of grey brown mildew.
2, fructification comes on go up in Chinese olive more, beginning is to carry ill spot of shape of the be soiled that show water on the head if really, development becomes Brown disease spot after, ill fruit is wet when humidity is big soft decay. The disease when air is dry submits dry corrupt form if really, fall off into fructification in advance.
3, blade comes on only then Yuxieji, blob of shape of water be soiled is shown first, expand outwards after circle, hemicycle, intimate circle or spot of irregular dust-colour a serious illness, spread to full page finally, blade is cankered, withered dead, ill ministry often produces substance of dust-colour mildew form, come on later period is easy cause inchoate fallen leaves.
4, fruit handle fall victim, produce Brown disease spot first, when humidity is big, ill ministry produces layer of mildew of a gray.
Come on the rule:
Warm and wet environment is helpful for coming on. Content of damage of disease of Tian Kuai of big canopy continuous cropping is much, strawberry comes on early and heavy, disease only then see period make an appointment with 30 days than building canopy ground shift to an ealier time; Slant the fertilizer that apply ammonia, strawberry grows exuberant, face of blade is big and pale green have gray mold easily; Excessive close planting, help advance somebody's career raised path between fields is too small, old leaf of plant radical ministry is much, and seeper of earth of ridge in a field, aerate inside canopy undesirable metropolis guides cause come on serious. Bacterium of cause of disease basically gives birth to spore with cent, hypha body or bacterium nucleus are mixed in ill incomplete body the live through the winter in soil. When ambient conditions is appropriate, bacterium nucleus bud produces minute of unripe spore stalk and cent to give birth to spore; Indoor lunt and dew undertake air current of have the aid of of cent unripe spore, canopy transmission. Cent gives birth to spore to issue bud to produce bud pipe in appropriate temperature and humidity, invade strawberry plant through cut, this is the first time invade catch; Come on place divides unripe spore in the generation below damp environment, undertake be invadinged again catching. The temperature range that divides unripe spore bud is wider, the most comfortable temperature is 13 ～ 25 ℃ ; Capability of fight a drought is stronger, when Dan Meng is sent, ask to humidity very tall, the easiest in water bud, relative humidity under 95% not bud.
Agriculture prevents and cure:
One, choose admirable disease-resistant breed.
2, water drought rotate, or rotate of as vegetable as the mustard family, legume.
3, clear thoroughly after results ill incomplete body; Growth period excises ill leaf, ill fruit, Laoxie in time, outside taking a canopy bury greatly.
4, continuous cropping big canopy can use summertime high temperature to disinfect soil. Use film of ground of tall ridge in a field to enclothe help advance somebody's career.
Drug of referenced prevention and cure:
Nitrile of bacterium of cough up of · of 25% curb mildew hangs emulsion (low poison) use 167-208 milligram / kilogram sparge
Water of bacterium of acyl of Ding of · of 38% Zun aether is dispersive granule (low poison) use 1000-2000 times fluid sparge
Mildew of second of · of 26% Mi amine power water is dispersive granule (low poison) use 96-144 is overcome / mu sparge
Fu Meishuang of · of 50% different bacterium but wet sex powder (low poison) use 80-160 is overcome / mu sparge
