Will MAGNACIDE™ H herbicide hurt crops?
If applied according to the label, MAGNACIDE H herbicide will not damage any crops. The label allows applications up to 15 ppm with no restrictions on irrigation.
What happens to the aquatic weeds after a treatment?
Submersed aquatic weeds do not have a waxy cuticle or skin like a terrestrial weed or crop. MAGNACIDE H herbicide reacts with specific proteins in the aquatic weed cell membranes that are exposed due to this lack of a waxy cuticle. Once this reaction occurs, the cells of the plant rupture. Weeds become discolored and flaccid. As they lay down on the bottom of the canal, canal capacity increases, generally in 24 hours. The weeds disintegrate over the next several days.
Why do I have to have a pesticide applicators license to apply MAGNACIDE H herbicide?
MAGNACIDE H herbicide is designated by the US EPA as a "Restricted Use Pesticide" due to its inhalation hazard and aquatic toxicity. Federal and state laws require this product to be sold only to licensed pesticide applicators.
Will MAGNACIDE H herbicide kill fish?
Fish are very sensitive to this herbicide. They will be killed at concentrations less than those required for aquatic weed control. Studies have shown that fish can escape the treatments if a viable escape route exists. As a rule, MAGNACIDE H herbicide should not be used where fish are considered a resource.
We heard that MAGNACIDE H herbicide has a very strong odor. Does this cause any problems during or after an application?
The active ingredient in MAGNACIDE H herbicide is acrolein. It has a strong lachrymator, or tear producing effect. During an application, when mixed thoroughly with water, there is minimal odor. Air monitoring of actual applications has determined this level to be below permissible exposure levels as set by OSHA. In most cases, you will not even know it is present in the water.
Does MAGNACIDE H herbicide build up in soil or crops?
No. MAGNACIDE H herbicide is a unique chemical. It is very reactive and breaks down quickly in the environment. It reacts with organic matter, aquatic plants, and water itself. In soil, it adsorbs to the soil particles and immediately becomes inactive. The naturally occurring bacteria in the soil continue the breakdown to the final stage of carbon dioxide and water. In plants, what little chemical is absorbed is rapidly metabolized into naturally occurring plant materials. There are no harvest or plant back restrictions on crops or soil following an application of MAGNACIDE H herbicide.
How do I get training for my employees in the use of MAGNACIDE H herbicide?
Training is just a phone call away. Baker Hughes' crop protection chemical technical sales representatives set the standard for product stewardship in the agricultural chemical industry. Training programs are conducted annually at various locations in all the countries we operate in. New customers receive extensive in-field training. Our personnel are always available to any of our customers to assist in training on the use of MAGNACIDE H herbicide.
How far will each application travel in a canal?
One of the big advantages to using MAGNACIDE H herbicide is the long distances an application can travel. Many environmental factors will affect application distances such as organic content in the water, pH, abundance, and species of weed to name a few. Velocity is a key factor in getting the longest distance. The higher the velocity the more distance. A good rule of thumb is: in a good flowing canal with a velocity greater than 0.5 miles per hour and aquatic weeds 24 inches or less in length, one can expect control for 8 -12 miles.
What type of aquatic weeds will MAGNACIDE H herbicide control?
It is important to be able to classify the weeds you want to control. There are 3 main varieties of aquatic weeds:
Does MAGNACIDE H herbicide have any long term effects on people or the environment?
When properly applied, MAGNACIDE H herbicide does not have any adverse long term effects on people or the environment.
Baker Hughes has supported and maintained the EPA registration for more than 30 years. We have conducted many studies on this chemical, including lifetime studies of its carcinogenic and oncogenic potential. These studies revealed that the daily exposure to acrolein over the life of the animal models did not result in carcinogenicity.
As mentioned above, acrolein is a very reactive chemical. Whether in contact with air, water or soil, it degrades very quickly. The degradation process in both water and soil proceeds ultimately to carbon dioxide and water.
