New tools, methods needed to replace methyl bromide

An alternative to methyl bromide.

Chemical Alternatives to Methyl Bromide

Three soil fumigants were evaluated at a nursery in Georgia and one in South Carolina. Seedbed density and seedling development were compared among plots treated with tarped and not tarped dazomet at 140 and 280 lbs/ac, tarped and not tarped chloropicrin at 125 and 250 lbs/ac, tarped MC33 at 350 lbs/ac and non-fumigated plots. Differences among treatments occurred only in South Carolina where b...

Visceral Leishmaniasis: New Health Tools Are Needed

0590 V isceral leishmaniasis (VL), commonly known as kala-azar, from the Hindu vernacular, is a human systemic disease caused by parasitic protozoan species of the genus Leishmania. Transmitted by the bite of the tiny and seemingly innocuous female phlebotomine sandfl y (Figure 1), the parasite enters macrophages, where it multiplies and establishes the infection (Figure 2).

The final rule, issued 1 January 1994, freezes...
