2. Ukwakhiwa kwesikhunta esifanelekile sokuvimbela nokulawula ukugqwala yilezi: i-tebuconazole + tristrobin, i-difenoconazole + propiconazole + pyraclostrobin, epoxiconazole + pyraclostrobin, i-fenoconazole + pyraclostrobin Pyraclostrobin + Clostridium, njll.

3. Khetha imbewu yommbila ekwazi ukumelana nokugqwala

4. Yenza umsebenzi omuhle ekuvimbeleni ukugqwala kusenesikhathi, futhi ungafafaza ama-fungicides ukuvikela ukugqwala.
