July 2021 FAQ’s

Here’s the July 2021 Monthly FAQ blog. A run through of the questions that get thrown my way during the month. After all, if one person asks the question a lot of other people are thinking the same.

It’s been a fairly quite month this July, I suspect the decent growing conditions at the beginning of the month and the heat towards the middle and end of the month have been enough to keep people pretty occupied.

But theres been a few common themes:

Red Thread, Lack of Anthracnose and Acelepryn.


Q: I’m seeing a lot of Red thread – What would you recommend?

It’s that time of year when turf is stressed, weak and susceptible. Firstly I’d always say to look at your nutrition, Red thread is generally more prevalent in weak turf. An application of Nitrogen is often enough to reduce the pressure.

Seeing a lot of Red Thread - What should I do?

Instrata Elite now has Red Thread on the label so this on top of your Nitrogen application will give the best levels of control. Here’s a blog on what goes into getting additional disease on a existing products label….

Q: I haven’t seen much Anthracnose yet – have you?

Anthracnose is an annual challenge and whilst the damage shows itself during the backend of the summer the damage is done earlier in the year. This year turf growth was slow to start but as I write this (23rd July) we have seen some seriously sustained high temperatures.

I suspect this year the hot dry May with reduced maintenance was when the damage was done. Good maintenance practices and reducing stress through that period was the key to successful Anthracnose control this year.

Going into that heat I put a few blogs out looking at good practice in the hot weather check it a good summary out here…..

It’s great news that we haven’t seen much Anthracnose about yet, hopefully we’ve had lots of good management practices going on, higher HOC’s, top dressing and adequate nutrition.

Were not through the trouble period yet – in fact now is the time to make sure we hold on to all those strong management practices for as long as we can.

Using Ryder and Hicure during these stress periods will help also.

However – if you have problems, you want to know where to turn – Instrata Elite or FR321 are your best bet but it will only stop it progressing significantly further. The nature of Anthracnose means that if you can see damage then more plants will be infected and a fungicide will only protect the plants that how not yet been infected.

Q: Any News on Acelepryn for leatherJackets yet?

As I write (23rd July) we are still awaiting the Emergency Authorisation for Acelepryn for leatherjackets. We are hopeful that it will be granted and the moment we have positive news we’ll be sharing it along with best practice advice from our 2020 user trials.

Q: What interval should I use for Primo?

Simplest version – for the time strapped

  • Cool weather – every 4 – 5 weeks
  • Warm weather – every 10 – 14 days
  • In the middle – In the middle

Easy Version – for those who want to get the best out of there Primo

Follow the GDD tool and set a threshold for 200 GDD (Base temp 0c) but don’t worry if you miss it by a few days either way.

Complex version – For those with time on there hands and plenty of staff

Follow the GDD tool, finetune your own threshold for between 180 and 220 GDD (base temp 0c) and keep tweaking until you know what works for your site. Be prepared though whilst this may completely optimise your applications it comes with challenges such as spray windows, GDD windows falling on the weekend and inevitable sprayer breakdowns at the wrong time!

Q. Are you going to festival of turf?

Yes we did and it was great to catch up with some friends and see some people in real life again! That fell right during the hot period of the month, so putting up the stand was a little sweaty.

Here is a blog I’ve written about the Festival of Turf and handling turf heat.

Take care and enjoy the summer holidays
