The figures you are quoting are incorrect.
You can apply 750 gms metazachlor/year (e.g. Butisan/Sultan/Rapsan @ 1. 5 lts/ha)
The other restriction to be aware of is that no field should be treated with more than 1000 gms/ha of metazachlor over a 3 year period…. which is pretty difficult to do...
Looks like anthers are visible on some of those ears and I would anticipate more being visible in next 24 hours…. If the aim of your T3 is about reducing fusarium/michrodocium infection I would crack on tomorrow without hesitation.
Will do a mix for Chocolate Spot/Rust but ignore Downy Mildew if disease is absent or below 25% infection levels (might put a phosphite product in if its feels like the right thing to do at the time).
If no Chocolate Spot (or rust) present at the moment then happy to delay treatment for time...
Elatus won't touch Downy Mildew.
The only fungicide with approval (EAMU) for controlling Downy Mildew in beans is SL567A/Clayton Tine (other brands might be available). Full rate is 0.16 l/ha but many will apply at lower rates e.g. 0.125 - 0.15 l/ha to balance cost and efficacy. Threshold for...
I agree entirely.
Just think it can be misleading when comparisons are made between products or mixes without breaking down into constituent a.i's and quoting savings per hectare/acre without knowing exactly what rates (gms/ha of a.i's) have been used.
In theory all stacks up, risk vs. reward etc.
Still not seeing answers to my original point about buying Myresa+Cyrex cheaper vs. Revvystar though. Impossible to compare Revvstar vs. Myresa+Cyrex…. surely need to factor in Comet etc. for fair comparison?
Myresa 1.0 l/ha + Syrex 0.5 l/ha = 97...
Nice.
In that instance if Septoria was my main disease threat and I really thought 97 gms/ha of mefentrifluconazole was required (+ I had managed to buy MyResa+Syrex really well) I would match the Fluxapyroxad rate of Revvystar @ 1.0 l/ha…. which would mean Syrex @ 0.6 (0.633 l/ha if your being...
Difficult to answer with any certainty as I don’t walk your crops. Would need a bit more info to make an over-the-internet recommendation on crops I haven’t seen. In addition I dont know your varieties, spraying capacity or appetite to risk.
One would assume that if you are using Myresa @ 1.0...
Not Agrii, but why the witch hunt?
I have spent many hours working out a.i loadings of different fungicide mixes and am interested to know how some growers get Myresa+Syrex at a lower cost than Revvystar.
Difficult to compare a product with 2 a.i’s with a box offer delivering 3 a.i’s and still...
