chard Tips fr r O l om ri p A

Robert H. Beede UC Cooperative Extension Farm Advisor, Emeritus Monitor Bud Break and Bloom: I hope you were out watching and making some notes on bud break and bloom, which started around March 19 in the southern San Joaquin Valley. Kerman was showing green on March 24 in many locations. This is early evidence that the rest requirement of pistachio was pretty well, if not completely satisfied, and the unusually warm weather the week of March 21 produced a very rapid emergence from dormancy.

So, we are ready to rock, folks!

You will never learn anything about pistachios if you stay in the house and watch Dr. Phil! Make some notes about the dates that bud break—when early-, mid- and late-blooms occur. This tells you how strung out fruit set is and to what degree, if any, you were affected by inadequate chill. This information also gives you some indication of how strung out harvest maturity might be. If you installed the weather station I sent you for Christmas, make a file on your computer for temperature data occurring during bloom and early-fruit set. This will aid you in evaluating unexpected events during this most critical phase of orchard production. High and low temperatures are particularly concerning because they can affect the rate of germ tube growth of the pollen grain and subsequent fertilization.

Visual signs of good rest satisfaction are Peters developing ahead of Kerman, and the south side of east/west planted orchards developing faster than those on the north side. Research shows the male Peters has a higher chilling requirement than Kerman. Thus, when its rest requirement is fully satisfied, it can develop before the Kerman female tree. Complete rest satisfaction also results on the south side of the tree by pushing before or simultaneously with the north because the south side is subject to more heat in warm winters. With marginal chilling, the north side of the tree pushes

sooner because it is not as affected by the warmer winter temperatures due to its orientation to sunlight.

Cold and rainy weather will slow tree development due to lower heat units. I cannot print the words to describe my disappointment in growers who treated with Dormex, and made no effort to record its effect on leafing, bloom, fruit set, and harvest dates.

Disease Watch: If it rains a quarter inch or more during bloom, it may be necessary to apply a fungicide to control Botrytis and reduce Botryosphaeria inoculum. Remember– BOT is a HOT weather disease! It will NOT show up during bloom and fruit set! Wilting shoots in early April are Botryis, not BOT. The potential for these diseases depends upon past infection levels and repeated rain events. Dr. Themis Michailides has determined that 0.2 inches of rain and temperatures, at or above 550 F, constitutes a Botryosphaeria infection event. Your inoculum pressure can still be assessed by examining the base of old cluster rachises for blackened tissue, which extends into the one-year-old wood and looks like verticillium streaking from where the cluster attached to the branch. Infected old clusters also tend not to break cleanly from the shoot. Instead, they leave a stub when one attempts to knock them off. Also examine older wood for sunken areas that, when cut into, have blackened tissue running lengthwise in the limb. These represent old infections that can possess active pycnidia for up to six years. Remember, Botryosphaeria is primarily treated in mid-June and July in orchards with low- to moderate-inoculum levels. BOT symptoms also develop in the hot summer, NOT cool spring! Shoot wilting and collapsing in the early spring, is very likely Botrytis.

And YES, I DO know that I just stated that above!

Please do not ask why I said it twice! LOL!

Irrigation: If you filled your root zone in February, there is no need to irrigate until late-April or early-May, depending upon soil texture and effective rooting zone. The pistachio water requirement in non-saline soil is less than 1.5 inches for the entire month of April! Thus, a four-foot root zone near field capacity, with almost SIX inches of available water, provides plenty of water to until early-May. Those needing to apply nitrogen during April should keep the applied water to a minimum. Obviously, a cover crop or dense native vegetation consumes lots of water and requires irrigation of the trees much sooner. A cereal grain cover crop can use six inches of water between the months of January and March.

Nitrogen: Avoid heavy nitrogen applications before fruit set. Remember, early shoot growth and fruit development is all from STORED NITROGEN! A good nitrogen management program includes soil, plant and irrigation water N assessment. This means you should have samples taken of each so you can make a better assessment as to how much synthetic N needs to be applied to the soil to meet the plant/crop requirement. Some growers/consultants favor N application shortly after bud break. They support this early timing with the accurate statement that it takes about 14 days for ammonia-based fertilizers to convert to nitrate for uptake. Hence, they want the nitrate conversion completed by the time there is a sufficient leaf area for its uptake by transpiration. In my opinion, this practice assumes there is inadequate nitrogen stored in the tree and soil to meet the growth potential of the tree. Based upon UC nitrogen research, the pistachio tree’s ENTIRE seasonal N requirement for growth and development is only about 25 pounds. The bulk of the N requirement is associated with crop development, thus the nitrogen status of the tree, soil and irrigation water would have to be quite low to require N application at bud break. That said, there are orchards that respond to early fertilization.

Back off on the N applied this season if you find soil nitrate nitrogen levels above 35 ppm per foot in the root zone. Nitrate nitrogen levels in the irrigation water must also be considered in your budget. A 10 pm nitrate N level supplies 27 pounds of actual N per-acre foot of water applied.

Micronutrient Sprays: Fifty percent leaf expansion (late-April) is THE OPTIMAL time for zinc uptake! Use only 2 pounds of zinc sulfate 36 percent or the zinc product of your choice. Research by Patrick Brown and Qinglong Zhang indicates it is safe to add one-half pound of Copper EDTA or one pound of Solubor to the foliar zinc sulfate rate. Buffering this mixture to a pH of about 5 also improves zinc uptake by increasing the amount in solution. Acidification

should be done with citric acid (powder) rather than phosphoric buffer to prevent zinc phosphate precipitation. Many growers prefer to avoid the powders and apply liquid materials formulated for pistachios. Check with your supplier for suggestions, but be sure they have adequate amounts of copper, boron, and zinc. This is especially true of 2- and 3-year-old trees. Deficiencies severely limit canopy development and reduce early bearing potential. My experiences suggest second-leaf orchards are especially susceptible to micronutrient deficiency, partly because of all the tipping performed to create branching. Three sprays are often needed to prevent loss of canopy development during this critical training year.

Shriveling Flower Clusters do not necessarily indicate fungal infection. Clusters that remain green and shatter off the tree could be associated with low boron levels. Boron deficient leaves have crinkled edges but remain uniformly green and normal in size. Tissue levels less than 60 ppm, in May, suggests the need for boron fertilization. Boron is taken up by the leaves throughout the season, so application can be made at any time during the spring. Correcting severe deficiencies may require up to 2 ounces of Solubor PER TREE (16 lb/ac) soil applied over time! Depending upon the severity of deficiency, start with ½- to 1-ounce of Solubor equivalent per tree, and then assess the soil and tissue levels after six months. Apply more in ½-ounce increments to avoid excessive boron in the soil. Boron is phloem immobile, so it does not readily translocate up into the tissues of greatest need. This is why you have to go slow to avoid problems.

Pest Management: It is time to get out the beating tray and monitor for small plant bugs, which are the most common cause of epicarp lesion shortly after fruit set. Go to the UCIPM Pistachio website and study all the small plant bugs that can cause damage. Research shows that 20 percent or more lesion to the clusters can be compensated for by nuts setting that would have otherwise fallen off.

Typically, out of 150 flowers per female inflorescence, only about 10 percent actually set.

Work with a pest control advisor knowledgeable about pistachios to determine how much damage you can tolerate. Most growers do not want to see ANY epicarp lesion, so they apply a prophylactic pyrethroid spray shortly after fruit set to put their mind at ease. I hope I live long enough to witness us getting off the pyrethroid treadmill with softer, equally effective new insecticide chemistry! What a HUGE impact that would have on a more balanced orchard insect ecology!

Happy Farming!
