These are the same chemicals that
are released from metam-sodium
(Vyapam) and metam-potassium
(K-Pam), commonly used as
chemical fumigants. Sorghums
produce a cyanogenic glucoside
compound called Dhurrin that breaks
down to release toxic cyanide when
plant tissue is damaged.
PROTECT YOUR CHERRIES
NATURALLY
Biofumigant crops can
suppress soil borne
pests but are not a
full replacement for
chemical fumigants,
nor are they a substitute
for adequate rotations.
Research on the control of
Phytophthora capsici for cucurbit
crops (pumpkins, melons,
watermelons, squash) using
biofumigation with mustards has
been especially promising.
It is important to note that
success with biofumigant crops
depends on a number of factors.
The following are some suggestions
to achieve the best results:
* Plant biofumigant crop
varieties selected or bred
for higher levels of active
compounds if available.
An example is the Caliente
mustard products including
Caliente 61, 119, and 199.
Most recently, Caliente
Rojo has been released.
It has been bred to
produce up to 10% more
isothiocyanates and more
biomass in a shorter growth
period than Caliente 199.
Produce as much biomass
of the biofumigant crop
as possible. This requires
that you have a good stand,
fertility and sufficient
growing time. The more
biomass that is produced
and that is incorporated, the
more chemicals are released.
However, as plants mature,
they will reach a point
where levels of these active
chemicals decline, and you
should not let the plants go
to seed. There is also the
practical consideration that
it is difficult to do a good
job of incorporation with too
much biomass. With a crop
like sudangrass, this means
you cannot let it get too tall.
* For biofumigant mustards,
apply fertilizer at minimum
50 lbs an acre with nitrogen
with sulfur (ammonium
sulfate is recommended).
