With sales up 9.9 percent from last year, almond growers clearly have been busy taking care of their orchards. With success like that, it would seem growers have earned a break. But in reality, their year has just begun as they must get a few steps ahead of nature to fend off pests and diseases to protect future crops.
It Starts in Late Winter
Delayed dormant stage for almonds occurs in late winter. During that time, pests like the peach twig borer can be found snugly hibernating under the bark of young almond trees or in bark cracks. This should concern growers as, at the first sign of spring, peach twig borers will emerge very hungry, significantly damaging trees as they chew their way through the season.
To prevent or minimize the damage emerging peach twig borers can cause, growers should apply an insect growth regulator now. DIMILIN® 2L is an efficacious product that can be sprayed on trees before bloom. It’s easy on beneficials and remains on tree surfaces to continue protection through early bloom. As an added bonus, DIMILIN can also be added to fungicide sprays for convenient application.
Early Spring Conditions Spur Disease
Jacket rot, caused by infections from Botrytis cinerea, is a fungus that can impact orchards early in the growth season. Also known as Green fruit rot, it is almost always present in orchards, appearing as water-soaked brown spots on petals. Damage from the fungus can be extensive when conditions are cool and wet during bloom time. To help knock out the fungus before it can take hold, the experts at the University of California’s Pest Management Program recommend applying a fungicide at full bloom.
PH-D® is a unique broad-spectrum fungicide that can be used during bloom and post-bloom, but it can be used throughout the summer months as well. It features a unique mode of action that not only controls Jacket rot but also controls diseases that impact almonds in late spring and summer, including Alternaria leaf spot, Almond scab, Rust and Hull rot. The product works by interfering with chitin-building enzymes, thereby preventing cell wall construction, making it ideal to include in a rotational management program to aid in resistance management.
As Mother Nature never rests, almond growers must continually monitor their orchards for any signs of disease or pests that may negatively impact their crop. It can be an exhausting job, but actively observing orchard conditions and taking preventative measures like spraying fungicides and insecticides can help alleviate stress in the long run while protecting future yields.
