It’s starting, a few reports of cranefly beginning to hatch are coming in. In fact they started a couple of weeks back – particularly on sites that had reported early damage. These tend to be in the mildest areas of the country. I’m definitely seeing patterns between warmer sections of the country and levels of…

I’ve put a couple of blogs together recently about Leather Jackets that have prompted some discussion. A recent Online survey we did gathered some serious momentum (thank you everyone) and gained over 410 submissions – that’s well over 10% of the golf clubs in the UK and therefore pretty representative of what is going on.…

Over the Christmas holiday we began to see some LeatherJacket damage. In my last Blog I wrote about the journey the offending grubs have been on since birth. If you’re seeing damage or you feel there is a chance of LeatherJackets in your sward then having a good understanding of the population will help you…

It feels too soon but I was getting feedback of leatherjacket damage before Christmas on the South Coast. Peak flight was 15 weeks ago now and we’ve only just started to see some cold weather. The above chart shows how we’ve had some pretty good growth since the hatch until the Christmas period when the…

With LeatherJacket damage being reported and courses closed the question being asked is – should I aerate? Why do it? This is my first response to this question – what are you going to gain? Do you need to: Increase infiltration rates? Decrease OM content? Keep surface open? Or are you just doing it because…

This time last year we were about to see the peak of Cranefly hatching. It’ll be interesting to see if that repeats itself again this year or if we are already there. Keep logging at PestTracker so we can get a clear picture. Either way this is the period to apply Acelepryn. Assuming you’ve seen…

The pattern and timing of crane fly sightings remains the same this year as it did last year. The reports are coming in thick and fast now and the amount of you engaging in this citizen science data gathering exercise is amazing. Last season we saw the hatch start around the same time but then…

It’s started and pretty much at exactly the same time as last year. Sightings form course managers on PestTracker are on the up. I suspect we’ll see a similar pattern to last year and see the period of hatching stretched over the next 3 to 4 weeks. So assuming you’ve seen Cranefly hatching, the next…

There seems to be no obvious pattern in the location of the hatches this year. I was desperately hoping there would be. There are no obvious links to climatic differences. Again I was hoping there would be something! I’ve spoken to a few people who are reporting seeing nothing on the golf course but seeing…

In 2019 the second week of September was the week we began to see an increase in Cranefly Hatching. This is important to know because when applying Acelepryn we want to ensure the majority of Cranefly eggs are in the ground. The Emergency Authorisation has been extended to the end of October this year giving…
