La Niña conditions persisted during November, with negative sea surface temperature (SST) anomalies present across most of the central and eastern equatorial Pacific (Fig. 1). The Niño indices remained negative during November, except for the Niño1+2 index which reflected near-average SSTs in the extreme eastern Pacific late in the month (Fig. 2). Also, the upper-ocean heat content remained below average (Fig. 3) in association with cooler temperatures at depth (Fig. 4), although this cooling lessened somewhat during the month. Atmospheric convection remained suppressed over the central tropical Pacific and enhanced over part of Indonesia (Fig. 5). The low-level easterly winds remained enhanced in the west-central tropical Pacific, and upper- level westerly winds persisted across the tropical Pacific. However, these signals were masked at times by intra-seasonal activity. Overall, the ocean and atmosphere system during November reflected a continuation of weak La Niña conditions. The multi-model averages favor La Niña (3-month average Niño-3.4 index ≤ -0.5°C) to continue through December – February (DJF) 2016-17 (Fig.

The current citrus IPM guidelines have been established from years of experiments and experience in oranges, with no specific guidelines for mandarins. In the absence of re- search into key arthropod pest effects in mandarins, the assumption that the pest management practices for or- anges appropriately transfer for optimal production in mandarins has not been tested. We used a data mining or ‘ecoinformatics’ approach in which we compiled and analyzed production records collected by growers and pest control advisors to gain an overview of direct pest densities and their relationships with fruit damage for 202 commercial groves, each surveyed for 1–10 yr in the main production region of California. Pest densities were different among four commonly grown species of citrus marketed as mandarins (Citrus reticulata, C.

  • Varietal Update
    November 17, 2016 FRESH NEWSLETTER FOR A NEW SEASON We are pleased to introduce an updated grower newsletter format that continues to provide seasonal varietal information, report on Sunkist sales and marketing activities while also highlighting consumer and industry trends that inform our sales and marketing strategies. Our staff will continue to share important regulatory information with growers separately from the newsletter to ensure timely news is communicated with the necessary urgency. Additionally, we encourage grower members to leverage the industry resources noted at the end of this newsletter for regular updates on important industry issues. As always, your feedback is important to us. Please e-mail questions, comments and suggestions about the newsletter to [email protected]. VARIETAL UPDATE ORANGES The Valencia orange crop has finished as the Navel orange season ramps up. The Navel crop is starting off with very good flavor and internal color. Focus is currently on sizes 88 and smaller as we wait for the season to progress with better overall color and more sizing options. Organic Navel oranges have also started shipping, with good availability and slightly larger sizing than the conventional crop; organic navels are currently at an 88/72/113 peak. The first packs of Cara Cara Navel oranges are expected the week of November 21/28, with initial sizing projected to be 88/72/113/56. Blood oranges are expected to start shipping the week of December 5. LEMONS Demand for lemons continues to grow, with bookings ahead of the past two years. Shipments are currently from districts 1 (D1), 2 (D2) and 3 (D3).

  • Keeping Growers Informed Oranges: Lemons: Specialty Citrus: Grapefruit
    Keeping Growers Informed March 7, 2014 Oranges: Sales of Navel oranges picked up as weather moderated across the U.S. and we expect that trend to continue. Export demand also should remain strong over the next few weeks. Sizes are peaking 72/88/113s and 56s. Valencia exports are underway from Districts 1 (D1) and 3, moving at a steady pace and sizing in the 72s and smaller range. Sales of Organic Navels were up at steady pricing and in line with crop pacing. We see good volumes ahead and harvest will be geared toward demand. Cara Cara movement is steady, peaking on 72/88s and 56s. As for Moro (blood) oranges, all houses are now finished and another successful season is on the books. Lemons: Lemon movement, as it has been all season, is significantly better than our two previous seasons. Also, in the midst of Lent, we expect markets to be firmer. Peak sizes are currently 75s, 95s, 115s and 235s. Specialty Citrus: Sales of our Sunkist Smiles® Mandarins continue steady, with recent rains causing only minor harvest delays. Projections at this time show the majority of the D1 industry crop will be finished by the end of March, with only limited supplies going into April. Movement has been heaviest to size 28/32/24s. The end of another successful Pummelo season is in sight as we clean up all remaining supplies this week. Fruit quality and flavor are excellent for our Minneola Tangelo crop, now predominantly coming from D1. Demand, both export and domestic, remains steady. Sizes are peaking on 100s and smaller at a packout ratio of 85% SK vs.
