Vegetable sodden pole, a lot of vegetable grower choose daub law to prevent and cure. This method specific aim is strong, effect it may not be a bad idea. However many vegetable grower react recently, fruit of aftereffect of daub bine stalk is bad, disease still was not treated.
Why to rot pole is treated so hard? No matter use,not be drug daub actually, however when daub too careless, bring about sodden pole to be treated hard.
Above all, ill ministry was not blown before daub. Blow clean without will ill ministry when daub drug, this is an aspect that affects the result that use drug. Because ill ministry is cuticular cankered, if blow,go out sordid, apply drug in ill ministry surface layer only, drug acts well in surface layer only, interior still can continue to decay, the gender is sucked inside the drug that daub of a lot of vegetable grower uses especially very poor, for instance cupreous preparation. Ill ministry all around the place that is the easiest oversight, must blow clean.
Next, the time of daub did not master good. Daub sicken place had better choose the daub when sunshine air temperature is higher, if be in early morning or dusk daub drug, disease has a department always is damp, can affect result of prevention and cure. Outside dividing the attention on time, still can join in drug right amount fine dry earth and puissant sit fruit is clever, the destination that adds fine dry land is moisture absorption, film of the water after daub forms time weak point; Join puissant sit fruit is clever, can promote heal of ill ministry cut, ill to preventing, treat a disease advantageous.
Again, the step that use drug is single. When vegetable grower discovers sodden pole, meeting mix mushy drug daub is in to disease. Prevent and cure so, prevent and cure to the diseased or infected plant of discovery only the effect is good, the diseased or infected plant that does not have apparent symptom did not use drug, do not talk to go up effect of prevention and cure. Wait like bacterial sex disease, epidemic disease, it is the disease with very strong infectivity. So, still need to notice complete canopy sparge or sootiness after daub of diseased or infected plant, in order to prevent disease to all round patulous. After proposal diagnose disease is phyletic, rapid gush uses drug or specific aim ground smokes drug, undertake local daub again next, the effect is better.
