Plant-Parasitic Nematodes Plant-parasitic nematodes (PPN) are a group of microscopic, worm-like organisms that live in soil or plant tissues and cause damage to crop production. While some species infect aboveground plant parts such as leaves and stems, those of greatest concern across a wide range of vegetables are soil-dwelling species that feed on plant roots….Read more about Understanding Nematodes in Soils of Diversified Vegetable Farms in Indiana[Read More]

Diversified produce growers and u-pick operations are increasingly exploring cut-flower production as a way to broaden their markets and increase revenue. To support this interest, our team of Extension specialists and educators is establishing demonstration sites in Lafayette, Indianapolis, and Vincennes, spanning north-south Indiana. In this article, we share lessons we’ve learned from our vegetable-growing…Read more about Starting Cut-Flower from Seeds: Lessons Learned from Demonstration Sites[Read More]

Corn Earworm https://extension.entm.purdue.edu/veg/cornearworm/ Our dent corn is through with pollination, leaving only our late plantings of sweet corn as a resource for the abundant moths in the landscape. Our thresholds are back down to 1 moth per night AND green silk on the plant to trigger a pesticide application. Did you know that corn earworm…Read more about Insect Trapping Updates[Read More]

This means that for those of you who have late plantings of sweetcorn that have yet to silk, your threshold will drop back down to 1 moth per night on average to trigger an…Read more about Insect Trapping Updates[Read More]
Squash Vine Borer https://extension.entm.purdue.edu/veg/squash-vine-borer/ The number of participants reporting trap catches has declined dramatically. Clinton, Allen, and Henry Counties are consistently reporting 1-4 moths per night. It seems that these populations didn’t get the memo that they are supposed to coordinate their mating during one concentrated time point in the summer. Regardless, at this…Read more about Insect Trapping Updates[Read More]
If you are a high tunnel tomato grower, you may have encountered small, blotchy leaf mines (Figure 1) or tiny brown mottled moths (Figure 2) on your plants in the past few years. These tiny pests are the tomato pinworm, Keiferia lycopersicella (family Gelechiidae). They should not be confused with the leaf mining fly, Liromyza…Read more about Insect Spotlight: Tomato Pinworm[Read More]
A familiar and dreaded sight of any home gardener is to find their rose bushes in a state of disrepair. Leaves skeletonized, flowers destroyed, and the remains crawling with iridescent green and brown beetles. This is the result of a Japanese beetle infestation. Japanese beetles were introduced to the United States around the turn of…Read more about Insect Spotlight: Japanese Beetles[Read More]
Squash Vine Borer More information available at https://extension.entm.purdue.edu/veg/squash-vine-borer/ For those trappers who are currently reporting, we can see that our first generation of active adult moths is declining. Corn Earworm More information available at https://extension.entm.purdue.edu/veg/cornearworm/ Montgomery County is still holding the record (La Porte did get the closest), but counts have dropped dramatically. We are…Read more about Insect Trapping Updates[Read More]
