Veraison, the start of the fruit ripening process, signals the final opportunity for effective canopy management and fruit thinning in grapes. Once veraison has started, thinning and canopy management are far less effective in improving overall fruit quality. Growers should assess the need for fruit thinning by evaluating cluster number and size relative to shoot[Read More…]

Summer bearing brambles are showing the full extent of the freeze and frost damage from earlier this year. Many floricanes are failing to produce a decent crop. Primocanes are growing well and are initiating flowers now. Early types are beginning to bloom. Grape are at bunch closure with veraison not far away for early varieties.[Read More…]
First, my apologies for sending this out late. This was a relatively early year for strawberries and by now, most harvest is over. As soon as harvest is done, it’s time to begin the renovation process. Matted row strawberry plantings must be renovated each year to establish new crowns for the following year’s crop. For[Read More…]
Indiana Pesticide Clean Sweep Project is designed to collect and dispose of suspended, canceled, banned, unusable, opened, unopened or just unwanted pesticides (herbicides, insecticides, fungicides, rodenticides, miticides, etc.). It is sponsored by the Office of the Indiana State Chemist, with support from the U.S. EPA. The disposal service is free of charge up to 250[Read More…]
In Lafayette, fruit crops are progressing normally. Strawberry harvest is winding down and quite of bit of leaf spot is showing up. We have our first ripe fruit on summer red raspberries. All brambles are showing signs of freeze damage from the mid-March event. Weak and collapsing fruiting laterals are common. Grapes are from late[Read More…]
Canopy management is a critical production practice for improved sunlight exposure. Pulling shoots off the top of the rows improves sunlight exposure to the leaves at the base of the shoots. Those nodes will be the ones saved as spurs next year during pruning and sunlight improves bud fruitfulness and cane hardiness. Shoot positioning is[Read More…]
One of the most important management practices for production of blackberries and black raspberries is summer tipping of the primocanes. This practice removes the apical dominance of the shoot tip, resulting in several lateral branches below the tip, and a stronger primocane. Next year’s crop will primarily be produced from buds on the lateral branches,[Read More…]
The Office of the Indiana State Chemist has filed a Notice of Intent to Adopt a New Rule that will make most dicamba containing herbicides Restricted Use Products (RUP). This designation will allow the OISC to track sales of those herbicides. As many specialty crop growers know, dicamba is one of the growth regulator herbicides[Read More…]
Grapes in the southern half of the state will soon be reaching the critical pre-bloom stage, which is a key time to control important diseases such as black rot, downy mildew, and powdery mildew. The three or four sprays made from immediate pre-bloom to 4 weeks post bloom are critical for controlling fruit infections. Growers[Read More…]
