Leaf tissue testing (also called plant analysis) is the best option when deciding if and how much more nitrogen or other nutritional elements needed to meet expected yields. Leaf tissue testing can help identify any "hidden hunger" that might exist in the crop. A "hidden hunger" develops when a crop needs more of a given nutrient but has shown no visual deficiency symptoms.[...]
Female ambrosia beetle (Coleoptera: Curculoinidae, Scolytinae) may bore holes in peach trees usually at the site of lenticels. As an ambrosia beetle tunnels into the tree, she deposits fungal spores. [...]
If you were not able to apply all of the dormant sprays to control San Jose scale in your peach orchard, there are options in the form of in-season sprays.
Dr. Brett Blaauw entomologist with Georgia Extension recommends that you use Esteem (6 oz. per acre) or Centaur (34.5 oz. per acre) if active crawlers are found in the orchard. If you cannot find active crawlers, this may indicate that the i[...]
Inspection Report Week of May 6, 2018 - Florida wax scale is right on schedule. May 18 and August 23 have always stuck in my mind as the ideal times to spray, or at least look [...]
Insect pests can cause major crop loss or contamination if not managed timely. We are generally very careful about choosing the right insecticide, but we forget to check the condition of the spray equipment that leads to insect control failure even with the best of pro[...]
May 10, 2018 - In recent a few weeks, most of the south Alabama was warm and dry, mostly dry. We have not had any rainfall for over two weeks in a row and this is taking a toll on row crops. Many people cannot plant their dryland fields and the crops planted are suffering drought stress. I have received several calls and texts[...]
Armillaria root rot (ARR) disease in grapes is caused by the fungus Armillaria mellea that infects grapevine roots, killing the cambium, and decaying the underlying xylem. ARR is native to many regions and can infect hundreds of woody plants. Host plants include broad-leaved trees in oak woodlands and stands of conifers. Agronomic hosts include stone fruits, nut trees, currants, gooseberries, nu[...]
Pruning helps to maintain a balance between vegetative and reproductive growth. If you don't prune or prune very little, your tomato plants will produce excessive vegetative growth with reduced fruit size. Moderate pruning will leave your plants with shorter vines and larger fruit that will mature earlier.
Pruning combined with staking keeps vines and fruit off the ground, helping to control diseases.[...]
Inspection Report Week of April 16, 2018-
April 6, 2018: Aphids were seen on the tip of a camellia. Ants were tending them, collecting honeydew produced by the aphids. Two small fly maggots were also present. On April 9 the aphids were virtually gone. Parasitic wasps had killed many, turning them into incubators (mummies) for developing young. Fly larvae were growing big and fat on aphids. [...]
Water management is one of the most critical issues in modern agriculture. Water resource has been critical to farmers since the adv[...]
There are thousands of insects in residential ecosystems, most of which emerge in response to the weather, temperature in particular. Spring weather conditions can change considerably from year to year, so can the time to take action against a certain insect. For centuries, people have used plant phenology (blooms, leaf flush) as nature's signs to set up wasp traps and mend window screens to fend off house flies[...]
Soil health is the ability of soil to perform functions that support life on earth. It provides food, fiber, and energy to sustain human life. Soil also protects our natural resources by filtering water and decomposing harmful chemicals.
Properties of a Healthy Soil
I have been receiving a surprising number of questions on how to control slugs in greenhouses and high tunnels over the past few weeks. The cooler weather certainly favors them as well as the cloudy weather. Damage from snails and slugs can resemble that done by insect pests such as caterpillars and wireworms.
Slugs and snails are usually nocturnal so their damage is generally noticed before the pests are actually seen. Slugs a[...]
March 30, 2018 - Sweet Orange Scab (SOS) (Elsinoё australis) was recently detected from citrus samples submitted to the Auburn Plant Diagnostic Lab for a citrus disease screen from Fairhope. This is a federally regulated pathogen. SOS was first detected in Alabama October 2017 from a reside[...]
Asian pears are considerably different from the old hard home-grown varieties like 'Keiffer' and 'Orient'. Asian pears have a distinct, but pear-like taste and they have a crisp texture, much like a good apple. Many Asian pear varieties also have an apple-like shape of the fruit and this combination of taste, texture and shape causes many people to refer to them as "apple-pears." They are als[...]
