What is the measure per gallon of orthene

[Ricardo in PR]

What is the measure of Orthene per gallon needed to kill hard brown scale and star scale? I also have one plant that has some yellow scale that I had never seen before.

The answer was a teaspoon per gallon. The application of this pesticide did devastate the scale population. However since a dead scale looks pretty much like a live one it took months for the effect to become evident as the dead scales eventually fell from the leaves.

It depends on what the concentration of your original Orthene concentrate is. I used to get 75% acephate, now the standard seems to be 97%, which means you only need about 3/4 of what was needed of the 75% stuff.

A truly remarkable thing was that nowhere in the label of the package there was even the faintest indication of a dosage or proportion of use. I had never seen such a thing.

Hi Ricardo in PR,

Well,Materials (Table 3) used for mound drenches are formulated as liquids. A specified amount is mixed with a gallon of water, and the solution is slowly poured into the mound. It will generally take one gallon of solution to give adequate penetration into the mound. A sprinkling can is a good container to use for this treatment. One of the most common complaints that one hears about drenches is that "they don't work--the ants only move from one area to the next." At any given time, ten to twenty percent of the ants may be out foraging, and they will not reenter a treated mound. These "displaced" ants will start a new mound (fire ants have a strong mound building urge) somewhere in the vicinity of the treated mound; however, if the treatment was successful, this "displacement" mound will not have a queen. Simply treat this mound since the number of ants will be greatly reduced.

Thanks

Ricardo, I don't know if it's on your bottle, but on my bottle I had to peel the label up and the usage booklet was under the label.
