Is it safe to mix Captan+Immunox+insecticide ?

12 years ago

As the subject line reads..

Is it safe to mix Captan+Immunox+Triacide Once and done insecticide into the same sprayer ? It would help in saving time in spraying, but I'm just wondering if its safe to do so and not have the chemiclas interact badly with each other?

Any thoughts?

Using chemical spray has a very simple rule. If it says you can do it on the label, you can, if it does not mention it, you can not. Using any pesticide, requires following the directions on the label. Al

Premixing is a normal part of spraying fruit trees and you can be sure if there was a problem with the combination you mention it would have been well documented here as these are common ingrediants for growers using this forum.

I commonly mix those three chemicals with the exception of triazide, but I've mixed other pyrethroids with Cap and Im (myclobutanil).

The main issue you are likely to encounter is captan anywhere near oil. You can't mix the two and shouldn't even spray them within about 14 days of each other.

Labels are very cautious about this for liability reasons, recommending you try a sample branch and come back later, but in the real world damage as a result of mixing incompatible chemicals that are well known is not common.

Safely Use wood ash in organic fert mix?
Q

Wood Ash in the Garden. By Rosie Lerner,Extension Consumer Horticulturist "The chilly winds of winter will likely keep many a wood-burning stove glowing, leaving stove owners with the ashes to dispose of. Many gardening books advise throwing these ashes in the garden. But what affect do these ashes have on the garden?Wood ash does have fertilizer value, the amount varying somewhat with the species of wood being used. Generally, wood ash contains less than 10%potash, 1% phosphate and trace amounts of micro nutrients such as iron,manganese, boron, copper and zinc. Trace amounts of heavy metals such as lead, cadmium, nickel and chromium also may be present. Wood ashes do not contain nitrogen.The largest component of wood ash (about 25%) is calcium carbonate, a common liming material which increases soil alkalinity. Wood ash has a very fine particle size which causes it to react rapidly and completely in the soil.So although small amounts of nutrients are applied with wood ash, the main effect is that of a liming agent.Increasing the alkalinity of the soil does affect plant nutrition. Nutrients are most readily available to plants when the soil is slightly acidic. As soil alkalinity increases and the pH rises above 7.0, nutrients such as phosphorus,iron, boron, manganese, copper, zinc and potassium become chemically tied to the soil and less available for plant use.Applying small amounts of wood ash to most soils will not adversely affect your garden crops and the ash does help replenish some nutrients. But because wood ash increases soil pH, adding large amounts can do more harm than good. Keep in mind that wood ash which has been exposed to the weather, particularly rainfall, has lost a lot of its potency including nutrients.Specific recommendations for the use of wood ash in the garden are difficult to make because soil composition and reaction varies from garden to garden. Distinctly acidic soils (pH less that 5.5) will likely be improved by wood ash addition. Soils that are slightly acidic (pH 6.0 to 6.5) should not be harmed by the application of 20 pounds per 100 square feet, annually.However, if your soil is neutral or alkaline (pH greater than 7.0), find another way to dispose of the wood ash. If you donÂt know the acidity or alkalinity of your soil, have it tested for pH.Crop tolerance to alkaline soil also should be considered. Some plants such as asparagus and junipers are more tolerant of slightly alkaline conditions than "acid-loving" plants such as potatoes, rhododendrons, and blueberries.Wood ash should never be used on such acid-loving plants" Too much ash can increase pH or accumulate high levels of salts that can be harmful to some plants, so use ashes carefully. Wood ash has a NPK of 0-1-3

Have yall got a safe water bath receipoe for dilled mixed veggies

It doesn't really require a specific recipe. It is basically just mixed vegetable, salt, dill or pickling spices of choice, and vinegar. You just add dried dill to your taste. You can add dill to either of the recipes you are using or you can substitute the dried dill for one of the other dried herbs. Or you can take the Dilled Green Beans or the Dilled Carrots recipe and used mixed vegetables instead just as long as you use 1:1 vinegar to water as the minimum ratio you are fine. If you use straight vinegar you can use any vegetables you want. Dave

micronized sulfur and copper safe to mix?
Q
Comments (1)
Yes, sulfur can be mixed with copper. The only thing sulfur should not be mixed with is oil. You need to be careful when spraying copper. If your tree have leafed out, you can burn the leaves with copper due to copper phototoxicity. You need to look at the label/instructions how much copper can be used after trees break dormant. Sulfur you can spray anytime. Sulfur and copper are both fungicide. Copper usually is more effective. You can spray one without the other.

I should mention that what Calistoga says is not necessarily true, IMO. Chemical companies are responsible to the safety of their customers based primarily on the ingredients in the formula. You mix at your own risk from a legal perspective and they cannot be aware of all compatibility issues.

Yes it's very common to tank mix pesticides. In many cases, it's recommended by universities.

Captan and an SI fungicide like (myclobutanil) Immunox is an excellent example. SI fungicides are prone to develop resistance issues in commercial orchards. Mixing a fungicide with multiple modes of action (i.e. Captan) pretty much eliminates resistance issues.

Another reason for tank mixing are than for large acreages, it takes a significant amount of time and fuel to cover the acreage. There would be no reason to duplicate the use of those resources by making multiple passes with different compounds. Additionally, multiple passes could wash off crop protectants from the previous pass.

There are university charts that show the compatibility of various pesticides. Generally, incompatibility shows up as one pesticide causing another to precipitate out in the spray tank. Although rare (but still happens) the mixture can cause foliage burn to the plant tissues.

I'm 99% sure you'd be fine mixing Captan, Immunox, and Triazicide. Just make sure you follow the label rates.

All that said, why do you want to mix Captan and Immunox? Most backyard growers use either one or the other per application.

As I spray Immunox and Triazicide quite a bit, I knew that was safe. And, I've never seen anything to indicate adding Captan would be harmful. But, my question is the same as Olpea's... If not to prevent resistance, why do you need both Immunox and Captan fungicides at once? -Glenn

I want to apply both Immunox + Captan for all my trees: peach, apple and plum trees (maybe I'll add it to pear tree too). Yes, I could probably remove Immunox from the peach trees...but I rather error on the wrong side.

Should I only add Immunox to Apple trees, without Captan ? I'm in NJ.

If spraying peaches then I would not spray both fungicides.

If you are spraying apples then I assume you gong for rot and ceder rust. I've mixed Immunox and Triazicide. I've mixed Captan and Triazicide but not both fungicides and Triazicide. I noticed on apples VT recommends spraying a cover mix of
.0 tbsp Immunox 1.55%EC
plus
2.0 tbsp Captan 50W
plus
2.5 fl oz M-Pede
or
2 tbsp Thionex 50W
plus
2 fl oz permethrin 2.5%
or
2 tbsp esfenvalerate 0.425%
or
1.5 tsp Confirm T/O

I wouldn't use Captan for a few trees but I do worry about resistance enough to want the added and much tougher fungus lock of Captan. By lock, I mean the difficulty of fungus developing resistance. Once that happens with Immunox, which is an easy lock to pick, you've lost the most useful fungicide for apples.

Also if you've had a lot of apple scab issues the addition of Captan gives you added protection when you get rain in between applications, because it relocates to newly grown leaves (washes from one point to another). This is also one thing that probably makes it more dangerous in terms of human exposure.

I agree also that Captan is probably better for brown rot than Immunox but that is after scab and CAR season.
