Why now?September 16, 2024

Why do small, isolated areas of ABW damage show up in September?

It’s wet for most, ABW pressure still lowAugust 19, 2024

Annual bluegrass weevil pressure remains low, but it is not uncommon to see some activity in September and early October.

A change to WeevilTrak in 2024July 15, 2024

June and July have been difficult months for cool-season grasses. One positive note is that ABW pressure appears to be low.

Round 1 is over!June 5, 2024

This year, the Memorial Day holiday correlated with the first round of annual bluegrass weevil (ABW) damage in the Mid-Atlantic and Northeast.

Weather impacts and phenological indicators of ABW larvae in MayMay 13, 2024

We started to pick up on early instar larvae in our trial work outside of Philadelphia in late April and early May and the larval densities and range...

All signs point to ABW adults peaking in the Mid-AtlanticApril 15, 2024

For golf courses in the Mid-Atlantic region, there have been two dominating weather themes for April — and these are not the eclipse and earthquake.

Short sleeve shirts and then winter coats — what is going on with the weather and ABW?March 15, 2024

What does a warm, wet winter with an extremely warm week in the middle of March mean for annual bluegrass weevil (ABW) management?

2023 recap: Weather and its impact on ABW pressureSeptember 25, 2023

2023 will go down in every golf course superintendent’s head as an extremely wacky mixture of weather.

August WeevilTrak updateAugust 23, 2023

I have seen a few pockets of ABW damage over the past two to three weeks, but late summer and early autumn ABW activity can be impacted by agronomic inputs.

July WeevilTrak updateJuly 28, 2023

Green keeping can be a very humbling task, and ABW activity continues to be difficult to predict.

Where were the spring flush of growth and ABW (in some spots)?June 22, 2023

The golf course is subject to the effects of weather 365 days per year, and this year's wacky weather has surely impacted the activity of insects and disease pests.

Finally, some nice weather. Oh, and some ABW larvae are developing quickly!May 9, 2023

After weeks of scouting for ABW adults and larvae — and seeing mostly adults in sporadic densities — we have started to consistently pick up on mid-range...

All the signs point to peak overwintered adult activity in Philadelphia and South JerseyApril 18, 2023

In my scouting and trial work, ABW densities have picked up, but the populations are sporadic.

Start to "trak" the ABWMarch 2, 2023

For now, my advice would be to hang tight, let the spring unfold and plan your scouting for the 2023 season.

Calendar says September, does that mean ABW season is over?September 15, 2022

I continue to scout at many golf courses throughout the Northeast and Mid-Atlantic and only find select pockets of ABW damage and activity. Stay diligent...

Where are the weevils?August 8, 2022

July of 2022 will go down in the records as being very warm. Depending on your exact location there were more than 15 or 16 days where the low temperatures...

Hit or miss with ABW activityJuly 21, 2022

Currently, I am finding very low levels of adults, callow adults and all different stages of larvae in untreated turf in my trial areas.

ABW damage recap and emergence of the second wave of adultsJune 3, 2022

For most of you, the first round of ABW damage should be past the peak. It is important to continue to scout your golf course for larvae if you have made application(s).
