Mode of Action

Ethrel is plant growth regulator with systemic properties. It penetrates into the plant tissues, and is translocated and progressively decomposed to ethylene, which positively affects the growth process.

Crops and Stage of application:

• Mango (for breaking alternate bearing tendencies): First spray in mid-October or early November total 5 spray at fortnightly interval
• Mango (for flower induction): Commencing from early November total 5 sprays at weekly interval
• Mango (post-harvest treatment): Dip mature fruits in the solution for uniform ripening. One treatment is required
• Pineapple (for flower induction): 30-37 leaf stage or 10-12 months. One spray is required
• Coffee (Arabica & Robusta): For uniform ripening of berries, one spray at fly picking stage when 10-15% of berries have ripened
• Tomato (post-harvest treatment): Post-harvest treatment can be done by dipping once
• Rubber: March, August, September, November (four applications) brushing once in two months on the tapping cut of the bark
