Participate in the 2022 Office of the Indiana State Chemist (OISC) Pesticide Clean Sweep Project, which is designed to collect and dispose of suspended, canceled, banned, usable, opened, unopened or just unwanted pesticides (herbicides, insecticides, rodenticides, fungicides, miticides, etc.). This is a great opportunity to legally dispose of unwanted products at little or no cost.[Read More…]
Grapevines are in early stages of growth across the state, from bud break to 10 inch shoots. Significant shoot growth is expected with the warm weather predicted for this week. This is a very important time to maintain preventative control over major grape diseases including Phomopsis, black rot, powdery mildew and downy mildew. Fungicide application[Read More…]
Time flies and now we’re in May! I’m guessing that most fruit trees throughout the state are somewhere between bloom and petal fall, so now is the time for tree fruit producers to use mating disruption strategies against tree fruit pests, like codling moth and dogwood borer, especially if you’ve had issues with these insects[Read More…]

Remember that only about 5-10% fruit set is usually enough for a full crop. In other words, 90 out[Read More…]
Historically Stinger® herbicide application in Indiana strawberries was limited to post-harvest. A new 24(c) Special Local Needs Label now includes a spring application (Figure 1). Why does it matter? A spring application of Stinger® will help to manage certain difficult-to-control broadleaf weeds in the spring. This will reduce reliance on hand-weeding, reduce competition between[Read More…]
Spring temperatures It seems like spring is progressing slowly, and in some respects it is. At this time of the year, the rate of plant development depends largely on temperature. The warmer it is, the faster plants develop. Early in the season we hope for cool weather to slow down bud development. This is so[Read More…]
