The attention that there is young plant of autumn stubble chili in the home, cure of these affection

Current, autumn stubble chili is major already field planting. After seedling field planting, disease-resistant ability is weaker, disease is sent more, once do not prevent and cure to reach the designated position, often bring about disease to spread, the loss is severe. So, chili is young seedling stage easy what disease to produce? How to distinguish, how should prevent and cure again?

Remind vegetable grower to prevent two kinds of big disease that minatory chili seedling grows ahead of schedule: Virus disease is mixed dead.

Cent of chili virus disease is a lot of sort, common symptom has: Hua Xie, etiolation, necrotic with deformation.

Hua Xie is chili the the earliest, most general symptom appears on plant, main show appears for ill leaf thick green with weak green alternate with mottled. Differ according to serious degree, cent of beautiful Xie You is light Hua Xie and heavy Hua Xie. Lamina of light beautiful leaf is basic level off, heavy flower has bubble account spot, shrinkage on foliaceous lamina, face of blade often uneven.

Etiolation often is behaved become yellow apparently in heart leaf, tender leaf, make individual plant sometimes or local also have more Huang Xie, phenomenon of occurrence fallen leaves.

Necrotic constant expression changes for plant part organization brown is necrotic.

Deformation often is behaved for plant short, ramose grow in quantity, lamina turns a line into shape. Produce initial stage, diseased or infected plant is shown fragmentary distributing, as illness accentuation, show a drop piece distributing.

We had introduced the method that prevents virus disease a lot of times, here no longer give uncecessary details, the key introduces drug of prevention and cure.

Virus disease travels agency to suck type pest for thorn more, because this produces serious canopy room in virus disease, often whitening cootie, aphid is kill serious. Commonly used insect-resistant drug has powdery cootie absolutely clean (ester of couplet benzene chrysanthemum) , mu flourishing is special (ester of snail bug second) , Aimeile (Bi bug Lin) , firm especially (ester of snail bug second and Sai bug Lin) , Xi Ding bug, also can use 1 packet of Amixida + 2 packets of acute are gotten the better of, add water 20-25 kilogram, fill root or dip in seedling. When insect pest is serious, can use mu of flourishing spy + sparge of water of Ai Meile add.

Main component is the drug of disease of virus of prevention and cure two kinds: It is the nutrition that improves plant to fight a gender drug; The 2 drug that are passivation virus cause of disease. The drug these two kinds of types often is in using a process answer deserve to use, the end that such doing basically is to be in passivation virus while will promote plant to restore the way corp is growing.

Commonly used drug has too fight (0.5% a few Ding Ju candy) , poison of A of element of Ning Na mildew, virus, curb is greeted green etc, usable also hydrochloric acid 15ml of element of mildew of Ning Na of Lin guanidine 15g+ , A Tailing + polysaccharide of the treasure that overcome poison, 2% Xianggu mushroom + the drug recipe such as iron of Gao Xin chela.

Cause chili to die disease basically is earth spreads disease, although behave a symptom to differ somewhat, but collective the characteristic is have breed and transmission for carrier with soil. Accordingly, through improved soil, add apply biology bacterium fertilizer, form to go against the bacteria breeds and invade caught edaphic environment crucial.

In improved soil, on the foundation of fertilizer of bacterium of sound use biology, recipe of use chemistry drug undertakes chili dies prevention and cure, have fast, efficient advantage. Chili of prevention and cure of drug fill root is dead, vegetable grower can use the following recipes:

99% evil mildew are 3000 times cleverer + 72.2% general force overcomes water agent 800 times, fill root. Evil mildew spirit can prevent root rot of Bao of corrupt skin sickle; Cyanogen of Niao of spirit of frost of Pulike, armour, frost can prevent epidemic disease.

Make water of cyanogen of 50% chloric bromic different is 1500 times more acerbity, fill root. Acid of make water of cyanogen of chloric bromic different is dissoluble produce second chloric acid, second bromic acid, have strong oxidisability, can exterminate all sorts of bacterias effectively, earth of prevention and cure spreads disease, the result is right.

A rice amounts to aegis of 10 milliliter highlight on the west (spirit of frost of armour of essence of life and nitrile of cough up bacterium) 10 milliliter add 15 kilograms of water dip in seedling dish; Grow after 3 days, afore-mentioned dosage chase reoccupy a fill root, every fill 2, fluid of 3 two medicine; Etc sit rush along with water again after 3 fructification use drug, every mus of ground each 300 milliliter.
