Beneficial insects and bug banks
Establish rows a metre or so wide
at convenient intervals- at land
boundaries or on contour ridgesof
suitable predator host plants,
preferably perennials for ease of
management. Fennel, pigeon pea,
citronella are all useful. Avoid
killing predators by accepting
some crop damage and resisting
the impulse to spray outbreakswhen
possible. There is usually
enough for everyone, and in the
long term spraying is likely to be
counterproductive.
Beneficial Fungi
In much the same way as broad
spectrum insecticides like pyrethrum
and rotenone damage control
through killing predators, the main
fungicides allowed in organic
systems- sulphur and copper saltscan
kill beneficial fungi.
Trichoderma harzianum TH (and
other T varieties) are widely used in
seedbeds to control soil borne fungal
diseases (e.g. in tobacco seedbeds).
Selected strains are effective against
a wide range of plant pathogenic
fungi including Pythium spp.,
Rhizoctonia solani, Fusarium spp.,
Botrytis cinerea, Sclerotium rolfsii,
and Sclerotinia homoeocarpa, and
Gliocladium virens. Root zone
protection from fungal pathogens
is taken from seedbed soil with
transplants. The root structure of
treated plants is generally better
developed, and yields higher.
Seedbeds should be treated with
TH following manufacturer’s
recommendations, and direct
sown seeds can benefit from THincluding
rotation legumes such as
sunnhemp.
Harvesting
For distillation and drying, reaping
on a larger scale is done with a side
bar mower or forage harvester. For
fresh produce and smaller scale dry
and distillation production, sharp
sickles or knives are used. Field
hygiene - hand and implement
washing, avoidance of contact of
crop with soil, and storage protected
from contamination by rodent and
avian droppings, etc. – must be
properly managed
Organic wild harvesting
It is important that any enterprise
utilising plant material from the wild
ensures there is no over-harvesting
of wild plant populations or
environmental damage. Cultivation
