Tropical Fruit Discussion / Share your tips for spraying mango for PM control
« on: January 19, 2025, 02:06:24 PM »
I would like to get a discussion going and create an archive of lessons learned using the My4Sons sprayer. Some of the questions will be specific to the equipment to et the best value from it but some may be just about spraying with any other sprayer.
Here are some areas I hope people will share insights and suggestions about.
1) Which is the best nozzle to get a fine spray and minimize volume of mix used when spraying mango for PM)
2) How to maximize the battery life / charge when spraying - should I use the agitator intermittently or run it continuously?
3) When spraying mango canopy, is it desirable to spray from above (using a long wand) and let the spray fall on the panicle and leaves or spray upwards (from below). I know with a mister you want the spray form a mist that adheres to the underside and top side of the leaves. With a liquid spray, especially for PM, what is the objective?
Here are some generic spraying question examples?
1) When spraying for PM management, do you want to spray the entire canopy or the part of the canopy with panicles? Are you trying to spray the panicles or is the intent to spray the leaves?
2) Will PM transfer from unsprayed parts of the tree to sprayed parts?
3) Is it best to spray 1st thing in the morning with dew on the trees or wait till things are a little dryer, or perhaps spray at dusk
Here are some possibilities on what to spray
1) For mango and for PM control, is there value in alternating what is sprayed (avoiding resistance)
2) What can be alternated with sulfur, safely. What have you used, what was your your experience like?
3) When you alternate products, do you keep a spray cycle of 6 to 10 days still ?
4) If you have spray left over, do you throw it out or continue to apply spray until the tank is empty (past runoff on the tree)
