| IPM Compatibility: |
Per Requester: IPM fit is Unknown; Since ACC is a plant growth regulator, it is not likely to affect beneficials:05/26;
|
| Reasons for need: |
Flower and Fruit thinning. Flowering in mango trees is a complex physiological process governed by the interplay of environmental cues, genetic regulation and hormonal signaling. The shift in climate patterns has turned the once- predictable flowering of a mango tree into a complex physiological puzzle. Since environmental cues are becoming unreliable, we look toward internal regulators. ACC is a precursor of ethylene which promotes flower development and fruit set:05/26;
