High temps for spraying

[Tractor Boy]

Just wondering what people's thoughts are on spraying T3 sprays on wheat during these warm sunny days. Is a simple tebuconazole or prothioconazole on its own through a relatively fine spray going to cause much scorch with a 25C temp?

I would try to do it after about 6pm in the evening or start at first light and stop around 9 am when weather is hot . Or if you have good lighting at night.
Going to put our T3 spray on on thurs and friday weather permitting

Crack on, have you not seen the forecast?

I would only tend to worry if it was 25 plus and on the breezy side.

This. It depends on your spray capacity. Like Banana Bar I have a fair bit to cover so we will crack on as soon as the stuff turns up & we can get going. Only 2 1/2 weeks since T2 but I don't want to let fungicide protection slip.

The t3 efficacy against mycotoxins is best at early flower? The later it gets the more likely it is that it's only going to make you feel better rather than do the intended job.

It's all relative is it not?
Not had a day over 20C here, yet the sun is very strong and burning.

On the other hand, when I worked in Queensland, they waited till temperature dropped below 30C before going spraying as it was now 'cool'.

rarely gets below that here in summer. Just add more wetter so it doesn't evaporate

It depends on what you want to do. Foliar disease top up is 3 weeks post T2, usually mid flowering. A true fusarium control dose needs to go on at a high rate as soon as the ear has emerged.
