Harvest season is officially underway for Indiana’s 94,000 farmers, which means more slow-moving farm equipment will be on Indiana’s rural roads and highways. To keep Hoosiers safe this year, state agencies are asking motorists to be alert and patient, as they share the road with farm equipment this fall.
“The fall is an exciting time for all Hoosiers as the temperatures cool and the leaves turn colors. And Hoosier farmers share that excitement as they prepare to begin harvest,” said Lt. Gov. Suzanne Crouch, Indiana’s Secretary of Agriculture and Rural Development. “While traveling rural roads and highways this fall, remember to watch for large farm equipment moving between fields as they work to harvest the crops, and be sure to know the proper steps to safely navigate around.”
In 2022 four vehicles were involved in crashes with farm equipment in Indiana which resulted in one death, according to the National Highway Traffic Safety Administration.
“Moving farm equipment can be one of the most dangerous parts of a farmers job,” said Don Lamb, director of the Indiana State Department of Agriculture. “When motorists know how to safely navigate around farm equipment, our roads are safer. By working together, farmers and everyday Hoosiers can ensure they arrive safely to their destination.”
Farm equipment during harvest season could include tractors, combines, grain carts, grain wagons and large trucks hauling agricultural products. These vehicles are wide, sometimes taking up most of the road, and often travel at speeds no greater than 25 mph.
The following list includes several safety tips for motorists approaching large farm equipment:
- Farmers will pull over when they are able to let motorists pass, but it may take time for them to get to a safe place to do so.
- Be alert. Farm equipment is wide, sometimes taking up most of the road.
- Be careful when passing. Do not pass in a designated “No Passing Zone” or within 100 feet of any intersection, railroad grade crossing, bridge, elevation structure or tunnel.
- Do not try to pass a slow-moving vehicle on the left without ensuring that the vehicle is not planning a left turn. It may appear that the driver is pulling over for you to pass when it is actually preparing to turn. You will drive right into its path, endangering yourself and the farmer.
- Avoid tailgating, as some farm equipment might have to make sudden stops along the road.
- Allow plenty of time to get to a destination, be aware of alternate routes and avoid distractions.
“When you see farmers out working and moving from field to field, please be patient as they work to harvest their crops which are needed to help feed our communities and the world,” said Doug Carter, Indiana State Police Superintendent. “Let’s all work together to help ensure everyone’s safety on our roadways.”

Last week I found this weird mottling on Rudbeckia. I figured it was a virus, so I took it to get tested. Purdue Plant Diagnostic Lab (PPDL) sent a report back saying the plant was positive for tobacco streak virus along with the following statement: Although extension publications mention this virus on Rudbeckia and it is widely known on other crops, I cannot find journal publications documenting it on Rudbeckia. So, that was a pretty cool find!
Also, I came across four spirea plants that had weird but also cool mottling as well last week. Although we did not get the viral tests ($100 for each test), PPDL determined we were most likely looking at spirea yellow leaf spot virus.

I had a couple of interesting encounters this past week. The first thing I found while doing a USDA bee sample. After I had completed it, I was watching a varroa mite that was on a larva that I had knocked out of the frame. However, it was not the mite that captured my interest, but a small brown line that was moving. After observing it for a while it appeared to be a maggot or small worm of some description.
The only thing that I can hypothesize is that it was a bee louse larva. Bee lice (Braula coeca Nitzsch) are small wingless flies about the size of a varroa mite. They are generally overlooked by most beekeepers and are not considered a major hive pest. They are not all that well studied but the larvae generally are thought to feed on honey or pollen and can cause minor damage when they tunnel under the cappings of sealed honeycomb. If you want to learn more about them please follow this link to the University of Florida page for more information.
Upon further conversation with more knowledgeable people than myself, I no longer think this was a nematode of some description. I’m kicking myself for taking it out of the pan and leaving it on the hood of my vehicle because it ended up rolling off the hood and I couldn’t find it again.
A second interesting scenario last week happened while doing a nursery inspection. At the nursery, I ran across a very heavy infestation of tuliptree scale. The trees were blackened from sooty mold which was noticeable from 100 yards away. Upon closer inspection, a local beekeeper had put two hives under these trees for the pollination of some pumpkins that had been planted adjacent to the trees. Pretty much every flying thing that can sting was hanging around including European hornets, baldfaced hornets, yellow jackets, paper wasps, and bumble bees. The honeybees were pretty content to ignore the honeydew and were working the pumpkin flowers and some common milkweed around the edge of the field.
There was a pretty intense amount of competition for the honeydew and I witnessed more than one baldfaced hornet get taken out of the air by European hornets. There were several dead and dying baldfaced hornets under the trees and I spent some time watching the hive entrance hoping to get some photos of hornet aggression with bees. Unfortunately, the bees were proactive in defending the hive and wouldn’t let me sit close enough to the entrance to get good photos. I continued to try and get some more photos of hornets but after having multiple close calls of hornets fighting and dropping on me out of the trees and almost down my sweatshirt, I decided I had pushed my luck far enough.
Another interesting find was a moderately heavy patch of rough oak bullet galls on swamp white oaks. These too had lots of flying stinging things hanging around and there was pretty intense competition for the nectar being produced. Bullet galls are formed by cynipid wasps. The wasp larvae are able to induce their host to form the galls which they live in and feed on. The galls also have extrafloral nectaries which secrete nectar and attract other insects like ants and wasps. In this case, there was not that much ant activity, but the hornets were out in full force and also some wasps which I believe to be in the Tiphiidae family (possibly Tiphia pygidialis). These are similar to the photo I submitted a couple of weeks ago of the five banded thynnid wasp and they are parasitoids of beetle larvae. If you would like far more detail on this fascinating bullet galls/cynipid wasp complex I would encourage you to read this write up in the OSU Buckeye Yard & Garden onLine (BYGL) by Joe Boggs.
Lastly, I had a nursery change hands and the new owner was not aware that barberry (Berberis) including ones labeled “non-invasive” cannot be sold in Indiana under the Terrestrial Plant Rule and a stop sale was issued for these.

Fall is near and competition can be tough for the best resources. Honeybees (Apis spp.) and a soldier beetle (Chauliognathus pensylvanicus) all try to get the best from this compass flower (Silphium laciniatum).
Weather in the Midwest is a very fickle thing. With warm days and cool nights comes early fall color. Compound that with the intense heat and low humidity of the days to come and trees are going to be under a lot of stress. Many will likely begin to show signs of early senescence. However, it’s always a good idea to double check those trees with early fall color. As can be seen by these photos, sometimes that color is caused by an insect stressor. In this case, Japanese maple scale (Lopholeucaspis japonica) has gotten to extremely high levels. When levels get this high, it can be difficult to tell if there is more than a single species of scale present (there could be) and treatment is much more difficult.

Just sharing a couple of photos this week. Herbicide injury on grape and a parasitized tobacco hornworm caterpillar on tomato.
If you see a hornworm caterpillar on your tomato plant that looks like this – leave it! This caterpillar has been parasitized by a small wasp which inserts its eggs into the caterpillar. The growing wasp larvae inside the caterpillar will consume it from the inside out. The grown larvae will then form white oval cocoons for pupation on the outside of the caterpillar. Adult wasps will emerge and provide more natural enemies in your garden area for future seasons.

I’ve included a photo of oleander scale on jostaberry. These are armored scales, see this link for a management guide on scale insects.
I also had a nursery with a small outbreak of white-marked tussock moth (Orgyia leucostigma) caterpillars feeding on some crabapple trees. Early instar caterpillars will skeletonize leaves and as they grow larger they will consume whole sections of them. This moth overwinters in the egg stage and eggs are laid in a mass near cocoons. Outbreaks don’t usually require treatment on deciduous trees. However, since damage occurs quickly, outbreaks on conifers can cause extensive damage and warrant control.

A couple of interesting things to note this week. I happened upon a pair of polyphemus moths mating which is always a treat to see. I also happened upon a fairly heavy patch of a type of midrib leaf gall on shingle oaks.
As I have been reporting, I’m seeing more of the ever-present herbicide damage including oaks, redbud, Kentucky coffee trees, and river birch (only river birch is pictured below to save space). I had several comments and questions about herbicide damage from last week so I would point everyone to this document by Ohio State University explaining the issue.
I also only just spotted my first monarch two weeks ago and last week I found my first monarch caterpillar on some of my swamp milkweed. This past winter was the second lowest overwintering count for monarchs in Mexico. I harp on habitat a lot and many folks I talk with have a hard time wrapping their head around pollinator habitat planting and management. It just so happens that there is a pollinator habitat management workshop coming up on Sept. 24 from 8:30 a.m. until 3:30 p.m. in Danville. You can sign up for the workshop at this link.

Scale was the theme for this past week. It’s a great time to look for scale since populations should be high and at this time of year, there should be ample evidence of dieback or sooty-mold present. I found several different types of scale this week including gloomy scale, oystershell scale, and cottony maple scale.
I was also at a nursery with heavy herbicide damage. Even a section of the nursery that was completely surrounded by mature woods had extensive herbicide damage. This particular nursery also does not use any herbicide, which makes me think it’s volatilization as opposed to drift. The mature oaks in the woods were also heavily distorted.
I am going to start including links to bee talks that I recommend. Some of these will be more general talks, while others will cover more specific topics. Here’s the first: Reading the Comb – Randy Oliver

I am a sucker for a variegated plant at any garden center; my eye is immediately drawn to the chaotic mix of green/yellow/white. The leaves below stood out to me this week while completing inspections, and I’m going to share a little info about how they are formed in nature. The appearance of leaf variegation on an individual leaf arises because of a lack or void of the green pigment chlorophyll in some of the plant cells. The cell mutation that causes the variegation can either be inherited (genetic) or occur randomly (chimeric).
Plants with genetic variegation will “come true,” and the identified color change will be stable when the plant is propagated; in other words, the color pattern will be passed from plant to plant. Chimeric variegation occurs when some of the genetic code mutates, and you find more than one genotype growing together on the same plant. Leaves displaying a chimeric mutation in nature are difficult to stabilize and will usually die out quickly due to a lack of chlorophyll without human intervention to help them survive.
