Over the last week we have been getting a lot of calls about extremely high bean leaf beetle numbers. Most calls have come from the Northwest Delta region of the state. We have actually made bean leaf beetle targeted sprays on a number of acres in recent days. Yield loss is caused by defoliation and less frequently by pod feeding
There have been numerous reports lately of high numbers of corn earworm and sorghum webworm in grain sorghum. I have heard some reports of numbers as high as 10X threshold. It is critical to scout and treat as needed to control these pest. There are three species that make up the headworm complex in grain sorghum; the corn earworm (bollworm), fall armyworm, and the sorghum webworm.
Week 5 Scouting Report Graduate Student Nick Bateman is running a weekly insect scout line in soybeans for part of his PhD project. We will be reporting his numbers weekly on the blog. Only insect pest that are being found in
When it comes to scouting for sorghum midge I have found that very few people have the confidence to accurately find them. Most believe if they are not finding them that they must be missing them or doing something wrong. The
In just the last 3-5 there have been several reports of bollworms now showing up at threshold numbers in soybeans in the Delta region of the state. In many other areas of the Delta folks are reporting flushing extremely high
Stink bugs consisted of Brown, Green, and Southern Green stink bugs, with Green and Southern Green Stink bugs making up 75% of the total stink bugs caught. Loopers are starting to show up in R3 and later soybean in all counties listed but are in low numbers. We also were flushing numerous corn earworm moths in several fields in the Delta region.
There will be an impromptu sorghum midge scouting field day at the MSU Delta Research and Extension Center in Stoneville tomorrow (July 14, 2015) at 8:00 am. We will meet at the Capps Building at 8:00 am and then travel directly
Tarnished plant bug populations have continued to be high over the last couple weeks in the Delta. A lot of the cotton is at or near the bloom stage when it is most attractive to plant bugs.
Field days scheduled for next week will highlight crops with new and developing herbicide and insect trait technologies. These field days will be held at the following locations: Brooksville – July 15 The Row Crop Technology Showcase at Brooksville will
Stink bugs consisted of Brown, Green, and Southern Green stink bugs, with Green and Southern Green Stink bugs making up 95% of the total stink bugs caught. Egg masses of both Kudzu Bugs and Stink Bugs have been seen in both regions in R3 and later soybean.
We are now beginning to get numerous calls from around the state about sugarcane aphid infestations. Populations range from very low to well above threshold with treatments becoming more common this week. At this time aphids are being found in the Hills and
An agronomic crops turn row talk will be held at Cliff Heaton farms, just east of the intersection of Highway 61 and Highway 6 on July 9, 2015. The field day will be held in the cotton field
Stink bugs consisted of Brown, Green, and Southern Green stink bugs, with Green and Southern Green Stink bugs making up 85% of the total stink bugs caught. Some small corn earworm larvae were found in very low numbers in the Delta region.
Weekly Soybean Scouting Report for Mississippi Hills and Delta Region 6/22-6/26
Pre-registration is now open for the upcoming Row Crop Technology Showcase events hosted by Mississippi State University. These events will be held at the following locations: Dundee – Douglas and Chris Hood’s farm – July 7 Brooksville – MSU Black Belt
An agronomic crops field day will be held at Cliff Heaton farms, just east of the intersection of Highway 61 and Highway 6. The field day will be held in the cotton field on the south side of the road. MSU Extension Specialists will be present to discuss topics in corn, cotton, grain sorghum, peanut, rice and soybean.
As some of the earliest planted rice is getting close to heading, it is time to start thinking about rice stink bug. We have been sweeping headed grass around the Delta for the past two weeks to determine what kind of populations are around.
This is a recycled article from 2012 and slightly updated but it fits well with recent calls. Sentences in italics have been added or updated since original posting. I have been getting quite a few calls about whether or not
By Keri Collins Lewis MSU Ag Communications STARKVILLE, Miss. — “Just mentioning bees and pesticides in the same sentence is sure to get a buzz,” said Angus Catchot, an entomologist with the Mississippi State University Extension Service. Media skirmishes about
This year we have seen tremendous population growth and expansion of Kudzu bugs from previous years. We have treated some acres already that were at threshold and I am confident that there will be many more to come based on what we are seeing around the state including the Delta region.
Over the last 7-10 days reports of sugarcane aphids in grain sorghum are becoming more frequent across the state. To date, I am not aware of any applications going out yet but numbers within some fields are definitely increasing. So far I have had about 10 reports of findings from the Delta region ranging from Cleveland to south of Inverness.
Many calls have came in over the past week to ten days regarding mixing insecticides and herbicides and the resultant effects on crop safety. There are many factors that go into phytotoxicity observed on crops from pesticide applications; however, I will
Mississippi State University will be hosting 5 scout schools this year. We have transitioned over the years to make these trainings much more diverse than insect pest alone. This year we will be including insects, disease, fertility, weed identification, and
Over the last couple of weeks I have had numerous calls about caterpillar pest in young soybeans. Most of these have been concerning beans that are still in the vegetative stages (V2-V5). The species that are being found are bollworm, yellowstriped armyworm, green cloverworm, granulated cutworm, alfalfa caterpillar, cabbage looper, garden webworm, and yellowstriped armyworm.
Over the last few weeks we have received numerous calls about brown stink bugs in seedling corn in the Delta region of the state. Stink bugs attack corn by feeding through the stem or even down in the whorl of small corn plants. Typically the area where they feed becomes chlorotic due to enzymes in their saliva.
