Free program predicts when weeds
will emerge and how fast they will grow.
WeedCast is a
Windows-based software application that forecasts emergence and growth of 17
(list below). Developed by USDA-ARS researchers Cheryl
Reese and Frank Forcella, the program's concept is fairly simple: You enter
daily max-min temperatures and rainfall into a preformatted spreadsheet and
select environmental data such as soil type, water capacity, and previous crop
and tillage. WeedCast then generates tables and graphs forecasting emergence
potential, emergence timing and weed-seedling height. (Not all are available for
each weed species in the currently available Alpha version.)
should be treated as guides -- estimates based upon current understandings of
the biology of the various weed species, caution the application's authors.
Regular updates will improve predictions and add new weed species. Requires
IBM-compatible with a 80386 processor or higher (Pentium processors highly
recommended), hard drive with at least 8 megs available, 4 megs RAM, Windows
3.1 or Windows 95 and mouse.
