Recommended Crops & Dosage

Method of Application

• Apply KEEFUN as a foliar spray at the early stage of crop infestation for best results. 
• Ensure thorough and uniform coverage of the plant canopy as this is a contact insecticide. 
• Use adequate water volume — at least 200 litres per acre or more depending on crop canopy. 
• Rotate with insecticides having different modes of action to avoid resistance development. 
• Avoid spraying if rainfall is expected within 6 hours after application. 

Mode of Action

KEEFUN is a METI (Mitochondrial Electron Transfer Inhibitor) compound that affects pest mitochondria through contact and ingestion, disrupting energy production and resulting in pest death. 

Precautions & Safety
