What is thiodicarb?
thiodicarb is a carbamate insecticide and pesticide, which consists of two methomyl groups connected by amino nitrogen through sulfur molecules. The physical properties of this crystalline powder include color from white to burning and weak sulfur odor. While this carbamate is relatively stable in light and surrounding conditions, at temperatures for 100 degrees Celsius (212 degrees Fahrenheit) relatively easily degrades to several by -products, including dimethylsulphide and carbon dioxide. However, the main by -product of Thiodicarb decomposition is Methomyl, achieved by hydrolysis catalyzed by acidic or alkaline conditions.
The chemical name for Thiodicarb is 3.7,9,13-Tetramethyl-5,11-Dioxa-2,8,14-Trithia-4,7,12-Tetraazapenadeca-3,12-Diene-6,10-Dione. Thiodicarb, however, is also known for several alternative common names, including Bishomyl Thioether, carbamic acid and UC 51762, among other things. It is also sold under Trade Larvina. As an insecticide is thiodicarb effectiveAgainst eggs and larvae, even if they have to undergo treated leaves to be controlled. Strong larvae contamination may require higher applications than standard dose, but not to exceed 60 ounces (1.77 liters) per acre (4047 square meters) per season.
Thiocarb is formulated to include several liquid products and one powder that must be mixed with water before use. Application to agricultural crops can take place on the ground or from the air. Which crops are treated with thiodicarb depends on how this agent is registered for every condition. For example, in Florida Thiodicarb is registered as one of the insecticides that can be applied to sweet corn. Vkalifornia, thiodicarb can be used on head salad, leaf salad, spinach, corn and celery, as well as cotton.
thiodicarb is considered slightly toxic. Animal -based studies show that a metabolic by -productThiodicarb, potential carcinogen known as acetamide, is eventually formed by the disintegration of methomyl in the stomach. However, this substance is further metabolized and excreted as carbon dioxide by breathing and urination. Because toxicity tests have been performed only in animals, the long -term impact of carbamate pesticides on human health is still largely unknown.
carbamates such as thiodicarb, inhibit cholinesterase, which means that they disrupt the effects of certain enzymes involved in the functioning of the central nervous system. The symptoms of thiodicarb toxicity include increased salivation, headache, muscle weakness, dizziness, nausea, vomiting, abdominal cramps and rich sweating.
In the environment, the decomposition of thiodicarbv depends on sufficient aeration, microbial activity, temperature and soil density and pH. With a half -life less than seven days, Thiodicarb is not expected to accumulate in the environment or contaminate groundwater.
