Modern clonal rootstocks are the foundation-and literal roots– to modern apple growing. These rootstocks ensure growers have orchards of relatively small trees that can be densely planted and result in earlier and greater bearing than what was historically possible. This is an obvious improvement over waiting multiple decades for an orchard to become profitable. However, to become profitable, the tree needs to reach maturity and continue to yield—early maturity and early death precludes long-term sustainability. Many growers have replaced the standby rootstocks of Bud 9, M.9 clones, M.26, and Mark rootstock varieties in favor of the newer ‘replant tolerant’ Geneva rootstocks (G.11, G.41, G.935, G.210, G.969, G.890), B.10, B118, or the Vineland series. Unfortunately, growers need to know not just what a rootstock is capable of, but what its limitations are, as well. There are no silver bullets (and besides, they are only good for werewolves, and don’t work on[Read More…]
Even in the most successful and best run orchards, trees die. A small percent is considered the norm, and is unavoidable (accepting this is a different story). However, in some years, more trees have succumb than usual. Growers need to determine what caused tree death–or at least rule out some potential pests or pathogens that could spread throughout the orchard—in order to manage and mitigate damage. Fortunately or unfortunately, many tree problems are abiotic (not caused by insects or pathogens) and are due to a complex interaction of environmental conditions. Plant pathogens and pests may contribute to many of these problems, but may not be the root cause (pun intended). Since the beginning of this season, multiple problems were reported from orchards across the state. There are several ways in which the environment can adversely affect trees, almost all of which can occur within Indiana (and even in the same[Read More…]

Grapes are at early to mid-version across most parts of the state, which is about normal timing. There are few disease and insect problems at this stage due to the relatively dry June and early July. However, if we continue to get rainfall as we have experienced lately, expect some berry cracking and potential sour rot problems. Recall from the presentation at Hort Congress by Dr. Megan Hall a couple of years ago that managing fruit flies is critical to controlling sour rot. There are several options listed in the spray guide. Addition of Oxidate or Fracture to suppress yeasts and bacteria will also help. An upcoming webinar August 11 “Biology and management of post-veraison fruit rots” will cover the latest research and recommendations.
