Sunflowers are in the sun and in flower

Sunflowers are well in flower with the later sown crops catching up in the sun and heat, currently 30 degrees plus during the day.

Should we spray a fungicide against sclerotinia and botrytis?

Many are recommending that we do; my feeling is that it is unrealistic to expect a few grams of active to penetrate and translocate through such a large plant to do any good.

Also the average yield for nine of the top producers in Ukraine was 2.3MT/HA over the last two years with a range from 2.1 to 2.6MT/HA.

I just can’t see applying $60 to $70 worth of chemicals at this stage will be economic.
