What is the difference between amine and ester

These two formulations tend to differ in several aspects. The first difference is that ester formulations have higher vapor pressures and tend to volatilize more than amines. Secondly, amine formulations may provide slightly less weed control. Can you mix amine and ester? Chaser ester costs more than double what three-way amines do. Another advantage of esters is if it rains shortly after spraying.

Are there different types of 2,4-D? There are two types of 2,4-D used as aquatic herbicides: dimethyl amine salt and butoxyethyl ester. Both liquid and slow-release granular formulations are available. How does 2,4-D work? Herbicides that act this way are called auxin-type herbicides. Higher vapor pressures result in increased volatilization. A 6- to 8-hour rain-free period is suggested for the amine formulations, while the suggested rain-free period for the ester is one hour.

Quick Overview. It is formulated to protect most grassy lawns, turfs, and various crop areas from unwanted weeds. It can also be used to control unwanted aquatic weeds and trees. Nevertheless, in , the International Agency for Research on Cancer declared 2,4-D a possible human carcinogen, based on evidence that it damages human cells and, in a number of studies, caused cancer in laboratory animals.

Dow stated the product would be available in 15 US states and Canada for the crop season. Agent Orange was a mixture of two different herbicides: 2,4,5-T and 2,4-D as well as kerosene and diesel fuel.

How long does 2 4-D take to work? Typically within minutes, the plant will start to feel the effect of the herbicide and you will start to notice browning in 48 hours. Because it is a selective herbicide, 2,4-D kills clover without harming most species of turfgrass.

Do not use 2,4-D to kill clover if your yard is planted with St. As temperatures warm in early summer, turf managers should switch to amine formulations because they work as well as esters and amine formulations are less volatile than ester formulations, making them safer to use around landscape plantings.

Another concern that lawn care pros mention when applying weed controls is herbicide volatility. Volatility is the movement of an herbicide in the air as a gas or vapor. This is different than drift, which is the movement of airborne spray particles during the application.

Volatilization occurs after an application when the herbicide volatilizes or vaporizes and moves in the air as a gas. Volatility can increase in hot, dry conditions. The concern with volatilization is that herbicides might move off-target and cause damage to desirable ornamentals, fruits, vegetables and other plants. I used MCPA amine at a rate of 3. Did the job, just wanted to know if there was a safer formulation.

Don't follow the ester based is safer. Here is a link to the home page Well worth saving the link for everyone. You are logged in as a guest. Forums Classifieds Skins Language.

Ester vs Amine. View previous thread :: View next thread. Message format Flat Threaded Nested. Eastern Ontario. Looking at using some MCPA.

So what is the difference between the Ester and Amine formulations? When do I use what? I think it has been discussed here before, but I can't find it right quick. Esters are less volatile, work faster, antagonize less but cost slightly more. Amines are wimpy
