ECOSWING BOTANICAL FUNGICIDE
Gowan
EcoSwing is an extract from Swinglea glutinosa in the FRAC P-05 group.
It is preventative and curative and has some SAR capacity. EcoSwing
should be applied at the first sign of infection and again on a seven- to
10-day interval. EcoSwing is safe on most plants and compatible with
most fungicides and insecticides. Gowan does recommend using a small
jar test and spraying a test plant when using any new product or product
combination on your crop.
EcoSwing's primary mode of action is to act as a contact desiccant and
cell wall disruptor to the fungal hyphae. Preliminary research also suggests
that EcoSwing may aid in triggering innate plant responses to help boost

plant's natural defense mechanisms against fungal pathogens. Trial works
also shows efficacy on some foliar bacteria like Xanthomonas (see Table 2).
EcoSwing is labeled for indoor and outdoor, greenhouse food and nonfood
crops, vegetable, fruits, herbs, tree nuts, ornamental flowers, trees,
shrubs and plants, landscapes, parks, recreational areas, plants growing
in containers, interiorscapes, home and garden. It is labeled for nearly all
crop types including ornamentals.
BOTRYSTOP
BioWorks
BotryStop is a live spore preparation of a non-pathogenic saprophytic
fungus, Ulocladium oudemansii strain U3. BotryStop aggressively occupies
the same physical space and out-competes pathogens for the nutrients
and space on the dead and senescing plant tissue; it is a true antagonist.
With this mode of action, it is highly unlikely that resistance to BotryStop
will develop.
BotryStop is an organic biofungicide for the control of pathogens such
as Botrytis cinerea, Sclerotinia sclerotiorum and Monilinia spp. BotryStop
provides protection to blossoms, fruit and plant tissues form these related
fungal pathogens. The product has a four-hour REI. BioWorks has carefully
researched this living biological control pageant for compatibility with a
wide range or conventional and biopesticide products. This compatibility
can be found on their website. Since it is a living fungus, care must be taken
not to tank mix or rotate with something that can kill it. It is compatible
with most wetting agents and biopesticides. Some of the fungicides that
should not be mixed with BotryStop include: Heritage, CEASE, Daconil,
Palladium, Chipco 26019, Dithane and RootShield PLUS.
BotryStop is sensitive to heat and special care must be taken to maintain its
viabilkity. Shelf life of the product is 12 months when refrigerated - ideally
kept below 68° F. Do not freeze the product as it will damage the spores.
