In-Season Spray BMPs
|
|
|
|
Monitoring
|
|
If several twig strikes are seen on each tree by mid-April, in-season sprays should be applied for peach twig borer control timed to pheromone trap catches and the phenology model for peach twig borer. |

|
Drift
|
|
The ability to detect products in streams and rivers at parts per trillion levels leaves little room for error.
To prevent problems, equipment operators must take extra care when spraying near sensitive areas and bodies of water.
Shutoff equipment when making row turns.
Avoid spraying when wind is blowing toward waterways or other sensitive areas.
Leave buffer zone to protect sensitive areas.

Managing Irrigation Runoff
|
|
Tailwater return systems can alleviate excess runoff preventing runoff from moving into surface waters.
Use vegetative barriers (see dormant orchard field practices) to filter runoff prior to leaving site.
Use of drip irrigation has reduced or eliminated irrigation-induced runoff.

Cultural Controls
|
|
Reduce dusty conditions in orchards by oiling or watering roadways and maintaining a groundcover. Prevent water stress, as this condition results in higher mite populations and makes trees more susceptible to damage.
The use of broad-spectrum materials in-season, such as pyrethroids, carbamates, and organophosphates (unless organophosphate-resistant predator mites are present in the orchard); will often result in spider mite outbreaks.
