Anyone have experience with coragen? Did some fields couple days ago and seems to be working.

Fields sprayed with decis/matador had to be resprayed few days later when the other flush moved up. Anywhere from 150-800 worms per square meter when checking, pretty bad infestation. Some guys not even spraying. In for a big surprise.

used it a couple years ago for berthas. really worked good and safe for pollinators. and good residual

Knock on wood I haven't found one in the canola. Aphids in lentils and canary thats a whole nother story.

out counting tonite, lots of spraying going on for a week now , 2 helicopters and planes,
i still have leaf ,, so very little pod damage yet . hearing too of those spraying twice.
just east of here

i have been pulling a sq ft. of plants , beating them out ,
counts of 2 , 5,5,15,28,8,10,15, 18, 18,15, 12, a lot of 8 s and 15 counts .
pick up chem tommorow , some getting planes tomorrow, myself , like a few other neighbours, we plan to do our own.
unless i read it wrong , i thought the threshold was 15-20 sq. ft.
i better check again .


a lot of cocoons, mostlly , med. large size worms , and a few small ones

what would you guys use as a trample %. 120 ft. booms , i was thinking about 1 1/2 %

even if you said 40 bushell should equal . 6 bushell / acre x 10$ equals 6 $ acre
does it sound about right. esp with no fungicide tracks to follow

What size are your tires? The first number is the width of tread in millimetres.

We've found taking out a piece of white board into the field and cutting the stems above the leaves and banging on the board gives you much better indication of where the bugs are. Then bang out the leaf portion after to give your total count. You lose so much taking handul back to the truck and banging on the hood.

From what I can see last few days try to use coragen (seems in short supply) and leave the decis/matador in the retailers shed. We applied ours at 60 ml rate and seems to be working good. Last tank going on this morning. Could have done heavier rate for longer residual but first time using it so was skeptical.

Very good advice Herc. 👍

how important is time of day.
those were late evening counts,
tires are 380 s.
think the plane is 11-12 $ so maybe it almost pays

Jag those pics remind me of swathing short season canola , 30- 40 years ago , with the worms 2 inches thick on cutter bar
the worms built up on the rollers, stopping the canvas, you had to pull handfuls from under the canvas. as the
100s above your head on the reel crawled down your neck

You have 30.4" of straight line tire trample / 1440 inches of boom = .0211 loss. With headlands, turning and extra damage probably 2.5% crop loss is a good figure if your fields are relatively square and wide open. If your expecting a $500 an acre return your trample loss $12.50 an acre. I would call the plane!

We used Coragen seemed to work good from what we can see applied some by ground and had some applied by air

Arial applicators would not have been to polular in Leader if they would have sprayed this field that we rent beside the Leader School
