Anyone use low drift (like ABJ) twin cap nozzles for dessication or anything else that needs canopy penetration?
Theory is that 2 x 5 gal low drift nozzles work better than one 10gal nozzle ....

Been running hypro twin cap guardians for fungicide and dessicating. Work very well IMO. Whether or not it's better then a single nozzle, who knows?

I know most of the nozzle manufacturers are going to be testing in-lab and in-field results of twin caps and dual nozzle use.

Right now, not much testing has been done objectively to see what the actual benefits in the field are like.
I know the testing is planned to take 2-3 years to complete (as it is in crop/canopy as well), but it should answer a lot of questions.

I hear a lot of guys using two different 'weights' (ie. MR & SR series of Wilger tips) of tips as well in the dual/twin cap setting with good results or even having like 2/3 of the flow out one bigger tip and the 1/3 through a smaller tip to get a good mix of droplets.

As always though, you gotta take those with a grain of salt. With two flat fan tips, you will be having two different outlets for driftable fines. So, if you are generally in windy conditions at the farm, then you'd probably be better off using a larger tip and less drift that losing half of your chemical into the wind (or farmers emerging crops - like a few guys had to deal with in SK this year)

All in all, I've seen even a lot of guys switching to dual tip for in-crop applications as well.

We use a low drift twin outlet tip for a lot of things .
Teejet AITTJ60-? , they are an air induction 30 deg forward / 30 deg rearward tip , work very well for us in most conditions , we use them for pre plant burn down , herbicide application , fungicide / foliar on leaf , preharvest glyphosate etc etc .
For Fusariam Head Blight control we use their AI3070 tip, 30 deg forward / 70 deg rearward .

Only reason I say TeeJet is because a local dealer handles them , I am sure other tip manufactures will work just as good .

I am using the Greenleaf Turbodrop dual fans for in crop insecticide applications @ 10 gal to the acre with very good results. Will be using the same nozzles only in an 06 for 20 gal for defoliation in A. seed this fall. They are a AI nozzle with a 10 degree forward and 50 degree rearward configuration.

Thanks for response.

Followup question -- any view on how fast you can travel with the twin-cap nozzles and still get decent coverage of regloine with 10gal/ac? Would be nice to go at least 15mph :)

We have been using twin abj nozzles at 6 gals. (Two 3 gal nozzles). We found it works great for reglone in lentils and because of those results now use the twin 3s for all incrop and fungicide applications.

Have you ever done any side by side with reglone? Like, the twin 6 gps and than say a normal tip and 15 gap? Just curious, I will have to try it myself this year.

six gallons for reglone? I tried some at 10 with twin caps, was not happy did not get the stems dried out in thick lentils. 20 gallons with twin caps just works for me anyways.

We've been running hypro twin caps at 5gal/ac on everything for 5 years. Did a side by side comparison with the neighbours single 18 gal/ac tip last year with Reglone on Greenland lentils. Seeded the same day, at the same rate, with the same innoculant, desiccated on the same night and at the same time and with identical sprayers. I did 160 ac on one tank and he did 133.3 with three tanks/three fills. Ours were harvested 2 days ahead and left a cleaner field and a lot more dust. Same combines and headers… They had never believed us until then.

Same, we run Hypro .03 twins for desiccating (Reglone and RU) at 6.6gal/ac and have had good luck also have used ABJ .06 at 13gal/ac with no difference in dry down both at 18ish mph. we use .06 Hypro twins for all fungicides also have had good luck, do all other, burn off, incrop herbicides with ABJ .015 single fan at 3.3gal/ac also with very good luck, I will call it luck only because it may backfire someday....

Don't want to hijack the thread but any of you that are running low GPA do any insecticides in heavy canopy crops with hard to kill bugs like Lygus?

Just a note of interest we recently switched over to abj and find them to be a bit better overall nozzle than the hypros. Hypros seemed to plug more and it appears to use that abjs drift a little less. Just our thoughts

I believe you but to twin ABJ's for Fungicides and Dessication to control drift is out of my budget for spray tips :eek: ;)
