Tank-Mixing Chemicals

Dr. Eric Prostko with University of Georgia shared some information on tank-mixing pesticides:

Tank-mixing pesticides can be rather complicated especially when numerous products will be mixed.  Here are a few questions and answers based upon some recent inquiries that I have received:

1) Can I tank-mix Prowl EC and Prowl H20?

I have never have done this in my research plots but I recently conducted a small tank-mix test (Figure 1).  With good agitation, I did not observe any problems.  Do not mix these two herbicides together before putting in water.  They should be put in spray tank (already filled with water) separately.

Figure 1.  Prowl H20 3.8ASC + Prowl 3.33EC Tank-Mix (32 oz/A of each in 15 GPA, Prowl H20 was put in 1st)


2) Can I tank-mix dry and liquid Valor formulations together in a spray tank?

I have never done this either in my research plots but I conducted another small tank-mix test (Figure 2).  With good agitation, I did not observe any problems.  Remember, it is always a good idea to pre-slurry dry formulations in water before dumping into a large spray tank.

Figure 2.  Valor SX 51WG + Valor EZ 4L Tank-Mix (3 oz/A of each in 15 GPA)

3)  When tank-mixing various pesticides, what is the correct mixing order?  

The general formulation science mixing order is as follows:

a) water soluble bags (WSB)
b) water soluble granules (WSG)
c) water dispersible granules (WG, XP, DF)
d) wettable powders (WP)
e) water based suspension concentrates/aqueous flowables (SC, F)
f) water soluble concentrates (SL)
g) suspoemulsions (SE)
h) oil-based suspension concentrates (OD)
i) emulsifiable concentrates (EC)
j) surfactants, oils, adjuvants
k) soluble fertilizers
l) drift retardants

For those Millennials out there that sleep with their cell phones taped to their head or hands, there is an app called Mix-Tank (Precision Laboratories) that you might find useful (http://www.mixtankapp.com/). There might be some other apps out there that I am not yet aware of?

4) How do I mix Reflex and Gramoxone?

a) add 1/2 of the required amount of clean water into the spray tank
b) start up and maintain tank agitation
c) add NIS
d) add Reflex
e) add Gramoxone
f) add remaining amount of clean water

5) How do I mix Atrazine and Halex GT?

a) add 1/2 of the required amount of clean water into the spray tank and start/maintain agitation
b) add AMS (**only if water quality sample indicates need)
c) add NIS
d) add atrazine (make sure atrazine is fully dispersed before adding other products)
e) add Halex GT
f) add remaining amount of clean water

2017 Using Pesticides Wisely Training

If you attended a training in 2015 or 2016 and are registered, you do not have to take the training again unless you would like. Growers will need to have this training if they would like to make applications of dicamba or 2, 4-D to dicamba or 2,4-D tolerant cotton or soybeans. It is suggested not just the grower but anyone who will be applying this technology to attend the training. Attached below are the dates and locations offered.
