Protectorhml What is it?

• Protectorhml is a pure potassium soap
  manufactured from fractions of vegetable oils
  it is not and does not contain oil.
• Chemically it is a unique complex of fatty acids
  of potassium salts. No two soaps act in the same
  way, some may or may not be fungicidal,
  insecticidal, herbicidal or soluble.
• Fatty acids are naturally occurring in plants and
  animals. The fatty acids making up Protectorhml
  are identical to those contained in wine.

ProtectorhmlCompatible with ?

• Wettable Sulphur
• Copper hydroxide and oxide
• Potassium bicarbonate
• Seaweed and some fish extracts (not fish oils)
• Several biologicals note in most cases it is
  not cleared by other manufacturers.
• Commonly used with Captan and other chemicals -
  be aware of compatibility and alkaline hydrolysis.

4
ProtectorhmlNot compatible with ?

• Many trace element supplements, such as calcium
  based products or products that contain nitrogen
  as a synergist/sticker.
• Many chemicals and/or the adjuvants or other
  additives contained in them.
• There is about to be more information on the
  website. Hort Research compatibility studies with
  sodium bicarbonate.
• Precautions to apply-
• Avoid compounds that are not compatible with
  alkaline materials or suffer from alkaline
  hydrolysis.
• Undertake a jar test to check for flocculation
  or scum.
• Do not leave any spray mix sit for long periods
• Always rinse out spray tanks after use.

ProtectorhmlModes of action as an adjuvant

• Protector spreads its companion product better
  than the companion product would under normal
  spray conditions. (Slide 6)
• Protector when wet, gathers spores together.
  (Slide 8)
• Protector, as a potassium soap, provides some
  degree of UV protection. (Numerous scientific
  articles on internet)
• Protector has its own fungicidal and fungistatic
  activity.
• Protector when it dries is not immediately
  soluble again as it goes through a gel state.
  It requires more than a wet surface to move it
  off acting as a sticker .

Erinose Mite Control (PM7)

• Erinose mite was studied on the side of our
  powdery mildew studies.
• Best control was achieved by an application of 7
  lime sulphur to run off on trunks and cordons
  at woolly bud stage between the growth stages
  of photographs, left and centre. In Hawkes Bay,
  only once was required and no follow up was
  required the following season in both trial and
  commercial settings.
• All treatments following woolly bud suppressed
  rather than eradicated.
• Erinose Mite control improves with increased
• Sulphur Rate
• Water Rate
• and the inclusion of Protectorhml

Summary of Protectorhml efficacy against botrytis
(7 years)
data from 2002-03 seasons has not been
statistically analysed full field rate
applied at 750-1000l/ha (high volume) Figures in
parenthesis are the number of applications.
18
Late season efficacy of Protectorhml against
Botrytis
Four applications of ProtectorTM (2) were
applied post veraison to vines at the Lawn
Rd Research Centre, Hawkes Bay in the 2002-03
growing season to determine if late season only
applications reduced Botrytis bunch rot at
harvest.
Key finding ProtectorTM was at least as
effective as Captan and demonstrated late season
efficacy against Botrytis fruit infection.
