On March 23, 2020, Gov. Jay Inslee issued an Executive Order directing all state residents to remain at home, except for essential activities, such as grocery shopping, medical care, or working at a business deemed essential.
Agricultural and food production jobs are designated as an essential and critical infrastructure sector. You can review the full list of Essential Critical Infrastructure Workers online. If you work in a job listed as “essential,” the Governor’s proclamation permits you to travel to your job or as part of your job. If you do not see your work area on the list, there is an online form you can fill out to get clarification or petition to be added to the list.
If you have concerns about traveling or the movement of your employees during this “Stay Home, Stay Healthy” period, contact your local emergency management office. Contacts are available on this list of State, County, City, Tribal Emergency Coordinators maintained by the Washington Sta...
Chamberlin's Cashmere branch is hosting a grower meeting on Monday February 24, 2020 from 12:30-4:30 PM focusing on proper sprayer calibration and best practices to improve efficiency and accuracy of pesticide applications.
Put on in partnership with the WSDA Technical Services and Education Department and the WSDA Natural Resources Assessment Section, the workshop will be worth 4 education credits. For more information about the event, click HERE.
Please RSVP to the Cashmere office (509-663-7151 x3) or email email@example.com. Space is limited to the first 70 attendees so reply as soon as possible to ensure a seat!
Spray drift is one of the most important issues facing pesticide applicators. Movement to off-site locations can be caused by wind, poor calibration/adjustment, and operator error.
1) Select a nozzle that produces coarser droplets
Use droplets that are as coarse as practical to provide necessary coverage.
2) Use the lower end of the pressure range
Higher pressures generate many more small droplets (less than 100 microns). Under most conditions, do not exceed 40 to 45 psi.
3) Maintain a constant travel speed and pressure during spraying
If an automatic regulator is fitted, remember, small increases in speed result in large increases in pressure. The delivered air and spray must be given time to penetrate the canopy.
4) Lower boom height
Wind speed increases with height. If boom height is a few inches lower, off-target drift is reduced.
5) Increase nozzle size
Larger capacity nozzles reduce drift. If you use nozzles that put out 10 to 15 gallons per acre (GPA), increase to nozzles that put ou...
Now that spring has sprung, that means the orchards across the Northwest as buzzing with activity, and we’re not just talking about the bees. The Washington Tree Fruit Research Commission says now is a key time of the year for growers to maximize their production.
“The most important thing that they can do, to directly affect those parameters, are related to crop load management,” said WTFRC project manager, Tory Schmidt. “And at this time of year, when we’re talking about crop load management, we’re really talking about thinning.” Read full article HERE.
Plants need light, carbon dioxide (CO2), water (H2O), and minerals for their development, growth, and for producing quality fruit (Marschner 2002). Most nutrient uptake occurs through the roots, between bloom and the rapid vegetative growth phase. In most perennial tree fruit, however, initial Spring growth and early fruit development rely mainly on reserves accumulated the previous season (Weinbaum et al., 1984). There is evidence that Fall applications of nutrients can help in building up reserves for the subsequent year´s critical early growth (Nielsen et al 1996; Lang 2005).
The macronutrients nitrogen (N), potassium (K), phosphorous (P), calcium (Ca), magnesium (Mg) and sulfur (S), should always be managed through the soil, unless there are absorption problems such as poor root volume or alkalinity. Micronutrients, on the other hand, can be managed effectively and efficiently with foliar sprays, especially under low or high soil pH (below 6.0 and abo...
Weed control is an important part of integrated planning for overall management of nutrients, water, irrigation and other orchard pests.
This article by WSU Treefruit Estension Specialist, Timothy J. Smith (CLICK HERE TO READ) provides a good overview of the benefits of proper weed control, effective methods, product options and application considerations (including the importance of sprayer calibration!).
