The conveyor belts placed on the extremities of the harvester convey fruit to the main belt, then seamlessly conveys fruit to the bin with one single belt exchange. This self-propelled 4WD Fruit Harvester reduces picking time, labor costs and guarantees excellent results by moving fruit faster, more gently and more effi ciently. As the bin rotates the fruit is lowered gently into the bin as it fi lls.

Trident Agricultural Products can help you create that orchard. With 30+ years of experience, Trident is the Pacific Northwest's soil fumigation specialist. Trident offers custom application of Telone ® C-17, Telone C-35 and Pic-Clor 60. Applications can be made in tree fruit, hops, grapes, berries and nursery crops. ® Trademark of the Dow Chemical Company ("Dow") ϐǤ restricted use pesticide.

The label for all chlorpyrifos products allows for only pre-bloom applications (only as late as 1/2-inch green). Later applications will kill bees. Most growers have Lorsban- resistant rosy apple aphid, but this spray may in some cases help with control of this pest and also tarnished plant bug. San Jose scale San Jose scale is a relatively easy pest to control with many different control options added in the last ten years, Biddinger said. "It is a pest that is better prevented than cured." It is also a dangerous pest to leave uncontrolled. After a few years of heavy infestation, limbs and even small trees can be killed, and the percentage of infested fruit can reach more than 80 percent in only a season or two. He believes the resurgence of this pest is due to three things: disruption of biological control agents by BMSB sprays; a move away from the use of dormant oils; and a lack of thorough spray coverage from growers using low spray volumes or only a single side application. SJS is normally considered a secondary pest because it has been easily controlled with a dormant oil spray to supplement biological control agents, which consist mostly of various species of tiny chalcid wasps (Aphytis and Encarsia species) that attack the scale under their waxy covering and some predators that attack the mobile stage called crawlers, he said. These predators are generalists that eat many small insects and include minute pirate bugs (Anthocoridae), the predatory mite T. pyri, and predaceous mirid plant bugs. "This biological control, however, can easily be disrupted by some broad-spectrum insecticides such as pyrethroids, Lannate, and some neonicotinoid insecticides that are used for BMSB," he said. "I would guess from the recent flares of SJS due to late summer/fall BMSB sprays that it is the wasps attacking the overwintering generation of SJS that are the most affected by the sprays." Biddinger recommends that growers use oil spray applications alone or with an insecticide at the dormant to green-tip stage and use spray volumes of 100 gallons per acre or more on larger trees to control overwintering scale. Growers need to be very careful about the insecticides they use at this pre-bloom stage because those with residual or systemic activity can kills bees when bloom occurs. Insect growth regulators like Esteem (pyriproxyfen), Centaur (buprofezin), and Movento seem to be effective against scale and have fewer impacts on bees and other beneficial insects. •
