Greening effects of strobes in cereals

It seems to be accepted that strobes prolong greening of a crop. Are there any difference between strobes and is the effect still seen so much with their loss of activity? There appear to be a few papers but I can’t access them as I don’t have a subscription.

Greening effect of these fungicides is still noticeable, it is sort of separate to their disease activity. Other fungicides also have interesting physiological effects on crop plants. Some of the SDHI products used to demonstrate interesting effects on root growth. Of course, the strobilurins still show useful activity on diseases other than septoria which may be of interest to farmers in areas where septoria isn't the only threat.

As I understand it strobes have an effect of chlorophyll production. Most seems to stem back to one research paper. Just wondering if there was any more evidence?

The evidence will no doubt exist, only it will be proprietary and no one will release/publish it. In the ag-chem world the big companies patent and protect absolutely everything and anything, even if it has no immediate commercial value. Create a new material- immediately patent it even if they have no intention of bringing it to market.

I believe comet(?) has greening on the label and as such had to have some evidence somewhere that it worked? Anecdotally I think they probably do but whether this translates to extra yield I’m not sure. There are far more knowledgeable people than me on here…..

I always believed the extended greening effect but assumed it was simply down to disease control, removing the stresses of infection such that senescence is delayed. It was marked with strobes as they were by far superior fungicides when they first came out, and even today control some disease hence can still prolong GLA.

Used on oats here at flag leaf the whole plant was as green as grass except for the head. Grain was 12% moisture and the straw would have made silage. Can’t use roundup on milling oats so had to swath and wait a week for them to dry down.

100% correct. To have any claim on a pesticide label there has to be a whole raft of work done, replicated and then re-done over multiple years and multiple sites
 
The trick is that many many pesticides are taken up by crop pants and disrupt their metabolism as they have to be worked out of the system. This alone may be why anecdotally people see less lodging or stronger straw when using fungicides, or delayed senescence or increased root growth, etc. Some kind of physiological stress is placed on the plant and it responds in such a way to try and counter act it.
