As you begin thinking about your IPM scouting program for the new season, consider the value of field guide for proper identification of orchard pests and beneficials. The Tree Fruit Field Guide to Insect, Mite, and Disease Pests and Natural Enemies of Eastern North America includes 500 color photos, actual size drawings of pests, over 20 pages of diagnostic keys.
Upon occasion, commercial growers try to find information on growing an alternative crop and find that there just isn't much information available. One crop that has received a lot of good press lately has been Goji berry. We have very little experience with this crop here, so were fortunate enough to get some information from others who have.
Our berry good question this month brought to mind a number of other questions about fertilization that we are frequently asked. So more questions and answers follow this first question from Sarah Blevins, S.J. Blevins Berries, etc. Thanks for asking, Sarah!
Penn State was the first institution in the country to put its production guide up on line in the mid-1990s. The new 2014-2015 Tree Fruit Production Guide is available as a hard copy and also as a pdf with a table of contents hot linked to the appropriate sections in the guide and all the URLs to additional reference material also hot linked. To save postage, purchase a copy of the production guide at one of the 9 spring twilight meetings for fruit growers!
As stated on the pesticide label – the sprayer needs calibrated before you spray! The challenge with air blast sprayer (ABS) calibration is accurately and efficiently collecting and comparing nozzle output.
Since temperatures got as low as -6˚F locally this winter, we evaluated bud mortality of four varieties of peach growing in Adams County on Feb. 26, 2014. Given the colder sub-zero temperatures experienced this winter in parts of western and northern Pennsylvania, it is likely that flower bud mortality may be higher in these regions.
We continue to see some below zero temperatures that were preceded by warmer temperatures. During the past 30 days, there were 3 dates with temperatures below 0°F.
The Orchard Spray Record-Keeping Spreadsheet has been updated and is available at the Penn State Tree Fruit Production website (http://extension.psu.edu/plants/tree-fruit). New features include the addition of FRAC codes and pages for supplying additional information required by processors.
At the Mid-Atlantic Fruit and Vegetable Convention this year, the State Horticultural Association of Pennsylvania (SHAP) asked researchers to display posters so everyone can see the results of grower-funded research and extension projects. Industry support not only allows researchers and extension personnel to solve industry problems, but industry funding is becoming a requirement for hiring applied researchers and extension workers.
The 2014-2015 Penn State Tree Fruit Production Guide has been updated for the 2014 growing season. In our goal to make the guide as comprehensive as possible we have added sections on postharvest disease control, marketing, the Geneva rootstock series and native pollinators.
One option for avoiding injury from spotted wing drosophila is to plant earlier-maturing varieties. This article discusses some cultivars that might fit the bill.
A must-have investment for folks in the tree fruit business is the recently released Compendium of Apple and Pear Diseases and Pests, Second Edition. The first edition was published in 1990 and the second edition has evolved to be nearly double in size. My one word review of the second edition: awesome.
Just about a year ago Rich Marini posted a good article on the Effect of Pruning on Cold Hardiness of Fruit Trees (link below). In the article he talks about the effect of early winter pruning on cold hardiness. I have firsthand experience at Rock Springs on the effects of December pruning on peaches. In my tree fruit class one of the laboratory exercises is to have the students learn to prune peaches. Unfortunately, due to the time the course is offered it is necessary to prune the trees in December. Photo A shows the damage I usually observe the next spring from our pruning lessons in December.
Strawberry is an herbaceous perennial plant and it is fairly susceptible to low winter temperatures. An understanding of the cold acclimation process is important to delay mulch application until the plants have acclimated but before plants are exposed to injurious temperatures.
The "Berry Good Question" column is being re-launched as a joint Cornell/Penn State effort.
Q: Each year I question whether I'm putting straw mulch on my strawberries too early. Some years, I've waited too long (usually due to hunting season) - then we get snow and I can't get it on at all, so I'd like to mulch as early as I can. I've seen an assortment of recommendations – what should I go by? Thanks.
Early-season yield and packout predictions are useful for growers and packers to plan for adequate harvest labor and storage space, to obtain the appropriate numbers of bins for harvest, and to develop an orderly marketing plan. Fruit yield is a function of numbers of fruit per acre and the size of those fruit. To accurately predict yield, one must have an accurate estimate of the average number of fruit per acre and average fruit size. If one would like to predict fruit packout, then an estimate of the distribution of fruit size is also needed. Obtaining accurate estimates of fruit numbers and fruit size requires appropriate sampling schemes. The purpose of this article is to review the information in the scientific literature on estimating yield and fruit size along with suggestions for next steps.
Stinger, a selective, postemergence herbicide for control of broadleaf weeds, is now labeled for use on apples. It is especially effective against thistles, dandelion, nightshades, and goldenrod, with some activity against clovers. Its mode of action is somewhat similar to 2,4-D, acting as a synthetic auxin, and it is in the same HRAC category as triclopyr (Garlon®).
Like many people, you may have fallen into the trap of thinking, “I am a farmer, not a business person.” However, consider the amount of money you handle in a year – most small business owners would like to handle that much money in a year’s time. You are a business person, and as such, you need to plan for success!
Penn State Extension has planned nine educational meetings for tree fruit growers throughout Pennsylvania. The meetings are designed to address current challenges with the latest research based information.
