Diamond backs

Numbers are very high in this area . A new batch just hatched a few days ago.
Wilkie area as well
We are out cutting plots today and the numbers are way over threshold. 20-50 m2.
Most are just 1/4 in long but there are some bigger ones . A few in cucoon already from a few weeks ago .
I counted 10 little ones less than a 1/4 in in this picture alone ... hard to see in picture . All hanging from branches and pods .
We still have good green leaf material but the moved up yesterday

Ya , it is bad south of here to your area Jag .
I had three planes going here this morning . I hate insecticide but the numbers were too high .

[farmaholic]

Had a quick look here. Nothing to be alarmed about.....other than how shitty that canola crop looks at closer inspection!

Jag, Looks like your getting your moneys worth out of the chem anyway.
Odd one here, most I'm finding are in cocoon. Anyone know off hand how long there in the cocoon stage?
farma your right, a lot scarier looking at all the heat blast damage vs. D-backs.

Some spraying here. Plane and a few ground rigs going. Our numbers are way way below threshold in our canola. However our canola is all Nexera and Nexera has a higher sugar content which is less attractive to most pests. We also use some Alpine and humate which tends to raise sugar even more.

Some guys in the Wilkie area have sprayed 3 times already , they are that bad in areas

[Hopalong]

Canola Council scouting guide says economic threshold to spray is 20 to 30 larvae per tenth of a square metre at the pod stage.

[furrowtickler]

The numbers are 2-3 x that in areas around here . Mostly west of Paynton , and from the white wood hills south .
Basically the dry area from end of May till late July .

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.
