I hope the growing season is going well for all fruit producers! My team and several grower collaborators (thank you!) have been monitoring fruit insect pests this season in apple and blueberry, including codling moth, spotted-wing drosophila, and brown marmorated stink bugs. So, for this issue of Facts for Fancy Fruit I thought I would…Read more about Fruit insect monitoring updates[Read More]

For those growing delicious small fruits, including cherries, raspberries, blackberries, blueberries, and strawberries, on a U-pick farm or even your backyard, now is the time to be on the lookout for spotted-wing drosophila (SWD), especially if your berries are ripe or in the ripening stage.

Dacthal® flowable herbicide is currently produced by AMVAC Chemical Corporation and registered for use in numerous vegetable crops (Midwest Vegetable Production Guide (mwveguide.org)) and strawberry. It provides pre-emergence control of small-seed broadleaf weeds and grasses. Dacthal herbicide contains the active ingredient DCPA. On April 28, 2022 the United States Environmental Protection Agency issued a notice…Read more about Future of Dacthal® Herbicide Uncertain[Read More]
In the strawberry benchtop system in the greenhouses at Southwest Purdue Ag Center (SWPAC), we have been experiencing infestations in red berries of a small, clear larvae with a black head capsule. The larvae are often found in clusters on a single fruit and were difficult for us to identify. We encountered them in early…Read more about Fungus gnat larvae in strawberries[Read More]
Indiana seems to experience the entirety of US weather, sometimes in the same day. The recent spate of cool, wet weather has left apple scab one happy fungus (Fig. 1). Most of the state just underwent an extreme scab period, and unfortunately, few of us could do anything about it because of the combination of…Read more about Wet weather & apple scab[Read More]
We’re getting close to the time when growers need to make chemical thinning decisions – for many the most perplexing and risky decision they will make all year. This is usually a tricky call to make. Remember that only about 5-10% fruit set is usually enough for a full crop. In other words, 90 out…Read more about Chemical thinning[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 about Spring temperatures, pollination- a refresher[Read More]
Throughout the state, most of us are in some stage of tree fruit bloom and as fruit producers, you all know how important insect pollinators are for ensuring good fruit set and even quality! Whether you’re producing tree fruits, nuts, or small fruit (even grapes, although they aren’t dependent on insect pollinators), we know that…Read more about Protecting pollinators during bloom[Read More]
