Almonds: Growers are preparing for hull spilt. Weeds are being cleaned up and most growers are wrapping up fertilizer applications. As we reach triple-digit temperatures, be on the lookout for mites. GAR Bennett PCAs are spotting some mite hot spots throughout the Valley. Monitor your fire ant pressures as well and consult your PCA if treatments are needed.
Citrus: Some growers are monitoring and re-treating for thrips, but most fruit is past the danger stage for this pest. Treatment times for red scale have begun; consult your GAR Bennett PCA on applications and timings appropriate for your location. PCAs are seeing high populations of citricola scale. Continue to monitor for this pest and time treatments in June through July, into August. This is peak hatch time for this pest. Keep an eye out for cottony cushion scale as well and try not to treat too early for this pest. Vedalia beetles serve as a biological control for cottony cushion scale, however they tend to move out as temperatures increase. Some Satsuma and Cara Cara growers are treating for sunburn protection. Growers are monitoring for mites, continuing fertility treatments and cleaning up weeds.
Grapes: June calls for staying on top of powdery mildew and pests to ensure a great harvest. Be sure to keep your vineyards clean this month as powdery mildew may cause bunch rot issues later on. Powdery mildew has been spiking in the last few weeks; consult with your GAR Bennett PCA on treatment options and application timing. Worm and mite populations have been low. Leafhoppers and mealybugs have been spotted in the field as well as spiders.
Stone Fruit: Worm pressure has been normal so far this season. Oriental fruit moth (OFM) timing may start in a few days. Consult with you GAR Bennett PCA about possible mite treatments that can be added to the worm sprays or about applications in blocks that have already been harvested. Katydids have been found to migrate into certain fields as harvest time approaches, which requires extra sprays. Less common pests like squash bugs and stink bugs have also been reported this year.
Cherries: Growers are continuing to complete summer tasks such as pruning, topping and applying sunburn protection. We are continuing to supply and line up fertilizer applications dependent on field needs as we approach fruit differentiation. Weeds are being cleaned up and we are monitoring for mites. If you have a history of this pest, consult your GAR Bennett PCA for advice.
Pistachios: We are reaching the end of chinch bug issues on young trees. Last month, PCAs were spotting this pest on the west side near I-5. Botryosphaeria (BOT) sprays finished up about two weeks ago for some growers. If you didn’t spray, keep an eye on leaves and nuts for speckling. This is a critical time for proper irrigation. Be sure not to underirrigate as this may cause shells to not split. The more split shells we have at harvest, the better.
Walnuts: Codling moth, BOT and mite treatments are currently happening in the field. Some growers are also applying sunburn protection. Weeds are being cleaned up and growers are staying on top of their nutritional programs. If you are experiencing nutrient deficiencies in the field, contact your GAR Bennett PCA for advice and guidance.
Tomatoes: PCAs are keeping an eye out for beet armyworms, thrips and beet leafhoppers that carry curly top virus. Leaffeeds are being added in with these treatments based on PCA recommendations. Dusting sulfur is being applied for powdery mildew. As the fruit starts to size and ripen, you may want to consult your GAR Bennett PCA about sunburn protection. Growers are finishing up fertilizer applications. Harvest for this crop may begin the week of July 4.
Garlic: Some growers are applying glyphosates to clean up persistent weeds. We are waiting for harvest to begin for this crop.
Dehydrated Onions: Fungicides are being applied to control for downy mildew and purple blotch. Some growers are continuing to apply fertilizers to help size up the bulb.
Cotton: Several growers on the west side are beginning to spray lygus treatments. Consult your GAR Bennett PCA for expert advice.
Alfalfa Seed: Growers are currently treating for lygus. As bees are pollinating the seeds, be sure to consult with your GAR Bennett PCA on treatment products that are safe for the bees.
