Features
Copper humate is an organic copper low-toxic fungicide composed of humic acid, copper sulfate and auxiliary components. It is a chelated hydrophilic colloid. After being applied to the surface of fruit trees, copper ions are gradually released to play a bactericidal effect. The drug is weakly alkaline, and its chemical properties are relatively stable in alkaline solution. It is safe to use, has no drug hazard, low residue, and does not pollute the environment. In addition, humic acid can stimulate tissue growth and promote wound healing.
Applicable fruit trees and control objects
Copper humate is mainly used in fruit trees to prevent and control branch diseases. Such as rot and dry rot of apples and pears, gummosis of peaches, apricots, plums, and cherries, rot and dry rot of jujube trees, dry and blight of chestnut trees, rot of walnuts, rot of hawthorn, Citrus resinous disease, foot rot, etc.
use technology
Copper humate is mainly used to smear the diseased spots on the branches of fruit trees, and sometimes it is also used to protect the cuts of fruit trees after pruning (sealing agent).
(1) For branch diseases of apples, pears, jujubes, hawthorns and chestnuts, scrape off the lesions until the edges of the lesions are smooth and without thorns, and then apply the liquid medicine evenly on the surface of the lesions with a brush. The edge of the lesion is 2 to 4 cm, and the dosage is generally 200 grams of preparation per square meter.
(2) Gum flow disease of peaches, apricots, plums, and cherries Use a knife to gently scrape the gum flow area, and then apply the medicine evenly on the surface of the lesion. The application method and dosage are the same as "apple branch disease".
(3) Walnut rot disease First, use a knife to draw evenly on the surface of the lesion, with a distance of 0.5 cm between the knife edges, reaching as deep as the xylem; then apply the medicine evenly on the surface of the lesion. The application method and dosage are the same as "apple branch disease".
(4) Citrus resinous disease and foot rot first scrape off all the diseased tissues with a knife to make the area around the diseased spots smooth and free of burrs, and then apply the liquid medicine evenly on the surface of the diseased spots. The dosage is generally 300-500 grams of preparation per square meter. Precautions: This medicine does not need to be diluted, it can be applied directly, but the medicine should be stirred well before use. Applicable only to the branches of the tree body.
