In the days prior to the arrival of navel orangeworm (NOW), peach twig borer (PTB) posed the greatest insect threat to almond crops. This damaging pest continues to torment almond growers, and research suggests that nuts targeted by PTB are more attractive to NOW than are nuts that have not been compromised.
To limit damage caused by PTB, it’s critical for tree nut growers to stay on top of their control.
DiPel® Biological Insecticide is an excellent tool to start the season with because it helps preserve valuable beneficial populations and prevents insect pressure from building up early, giving beneficials a chance to flourish. Applying a (Bacillus thuringiensis) Bt insecticide such as DiPel at bloom can significantly reduce PTB strike counts, preserving the value and yield of your almond crop.
Studies show that a PTB larva will feed on average of 2–3 buds before it pupates, resulting in a tree with a large percentage of dead shoots and a significant loss in productivity. When applied at 30% emergence and again 7–10 days later at 80% emergence, DiPel stops larvae from feeding and minimizes crop damage.
Coverage is key to control. Check calibration and use sufficient spray volumes tin order to cover all sides of plant surfaces.
Incorporating DiPel into rotation or tank mixes with other insecticides can improve field performance and reduce cost while providing resistance management benefits.
DiPel is also compatible with fungicides, such as Quash®, for fewer trips through the orchard.
With a delayed dormant application, Seize™ Insect Growth Regulator also provides partial control of PTB, making Seize an ideal partner with DiPel in a soft-chemistry scale and PTB program.
