துத்தநாகக் (Zn) குறைபாடு

Class: ஊட்டச்சத்து குறைபாடுகள்
Common Name: துத்தநாகக் (Zn) குறைபாடு
Symptoms:

The Initial symptoms include interveinal chlorosis on young leaves, which can be similar to those of iron deficiency. In later stages of zinc deficiency, newly emerged leaves will likely to be narrow and remain small. Symptoms that might occur as the severity level increases are shortening of the internodes, necrotic spots, and bronzing of the leaves.

In Short:

Control Measures

மண்ணில் துத்தநாக சல்பேட் (ZnSO4) அல்லது துத்தநாக ஆக்சைடு (ZnO) சேர்க்கவும். காரத்தன்மை (உயர் pH) கொண்ட மண்ணில், துத்தநாகத்தின் கனிம வடிவத்துடன் ஒப்பிடும்போது துத்தநாகத்தின் கலந்த வடிவம் (Zn-EDTA) ஒரு ஆதாயத்தைக் கொண்டிருக்கிறது.

துத்தநாக சல்பேட் அல்லது செலேட்டைத் தெளிப்பது ஒரு மாற்று முறையாகும்.

Caution and careful notice should be taken when using any plant protection products (insecticides, fungicides, and herbicides). It is the grower’s sole responsibility to keep track of the legal uses and permissions with respect to the laws in their country and destination markets. Always read the instructions written on labels, and in a case of contradiction, work in accordance to the product label. Keep in mind that information written on the label usually applies to local markets. Pest control products intended for organic farming are generally considered to be less effective in comparison to conventional products. When dealing with organic, biologic, and to some extent a small number of conventional chemical products, a complete eradication of a pest or disease will often require several iterations of a specific treatment or combination of treatments.
