🌿 Organic Pest & Disease Management | જૈવિક જીવાત અને રોગ નિયંત્રણ

Introduction | પરિચય

Organic farming is not just about growing crops without synthetic chemicals. It is about maintaining ecological balance, protecting beneficial insects, improving soil health and managing pests naturally.

પ્રાકૃતિક ખેતીમાં પાકને જીવાત અને રોગથી બચાવવા માટે કુદરતી સંસાધનો, વનસ્પતિ આધારિત દવાઓ અને ઉપયોગી સૂક્ષ્મજીવોનો ઉપયોગ કરવામાં આવે છે.

જૈવિક જીવાત અને રોગ નિયંત્રણનો મુખ્ય હેતુ જીવાતોનો સંપૂર્ણ નાશ કરવાનો નથી, પરંતુ તેમની સંખ્યા આર્થિક નુકસાનની મર્યાદાથી નીચે રાખવાનો છે.

9. Frequently Asked Questions (FAQs)

Q1. What is the safest way to control pests in organic gardening?

Start with regular monitoring, hand removal, physical barriers, sticky traps and conservation of beneficial insects.

Q2. Can neem oil control all insects?

No. Neem oil is useful against certain pests but does not control every insect or disease.

Q3. What is the difference between Neem Oil and Neem Astra?

Neem oil is an extracted oil-based product, whereas Neem Astra is a traditional fermented botanical preparation.

Q4. Can Trichoderma control all fungal diseases?

No. Trichoderma helps manage certain soil-borne pathogens but is not effective against every fungal disease.

Q5. What is the role of yellow sticky traps?

They help monitor and trap certain flying insects, particularly whiteflies and aphids.
