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.

Attention all Oregon growers! The new Oregon OSHA Application Exclusion Zone (AEZ) Rule goes into effect January 1st. HERE is a good overview of the new rule for reference. Also note, Oregon OSHA offers technical experts to help understand rules, as well as on-site, confidential and no-cost consultation services (https://osha.oregon.gov/consult/Pages/index.aspx). Your Chamberlin consultants are always on call to answer any questions about rules and regulations that apply to our products. 

Why apply nutrients in the Fall?

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!). 

Tis the season for vole control. Click HERE to read an informative paper about effective vole pest control methods for tree-fruit orchards. If you need help battling mice in your orchard, your Chamberlin Crop Adviser is here to help.

A new pilot program by the Plant and Food Research in New Zealand is releasing sterile coddling moths into apple orchards (via drones) to reduce the pest population. The first season has shown more than a 90% reduction in coddling moths. According to Plant and Food Research Scientist, Dr. Jim Walker, "within two seasons we expect the coddling moth population to be eliminated from these test orchards." This sterile insect technique shows significant potential for the apple industry and future management of pest insect populations around the world.

Chamberlin Agriculture is please to bring Hydralada machines to its growers--mobile elevated orchard work platforms that allow more efficient (and safer) harvesting, pruning and elevated construction work including overhead protective netting and artificial shelters. Self-propelled by foot controls, the compact platforms leave operators hands-free to pick fruit and are maneuverable in tight rows and spaces.

Independent studies have confirmed that Hydralada orchard platforms can significantly increase worker output year round, from pruning trees in the winter through to harvest. In fact, one person working from a Hydralada machine in 15-foot apple trees can carry out the equivalent work of three to four people on conventional step ladders.

With labor shortage and worker safety being two very important considerations in today's modern orchards, Hydralada platforms are valuable tools for growers. Contact Jake Carson for additional inform
