The postharvest preservation solution

The Product

PHILABUSTER® combines the active ingredients imazalil sulfate and pyrimethanil, two fungicides with different

modes of action and a high level of efficacy. The active ingredients show synergistic effects against a variety of

pathogens and as a result it offers a high-level control of a broad spectrum of postharvest diseases. The product

offers as well a preventive, curative as anti-sporulation activity.

The product contains 200 g/l pyrimethanil and 200 g/l imazalil and is formulated as a Suspension Concentrate (SC).

Application

PHILABUSTER® can be used in dip and wash tanks, drenchers, aqueous line spray and in wax line spray systems.

The objective is to obtain an even cover of the fruit surface with a sufficient residue for qualitative long term

storage and a good shelf life afterwards.

For optimal use, treat within 24 hours after harvest.

The Mode of Action

The biochemical mode of action of the

combination product PHILABUSTER® is

related to its two active ingredients.

Pyrimethanil is an anilinopyrimidine

fungicide (Group 9) that interferes with

the secretion of enzymes necessary

for infection by several postharvest

pathogens, while imazalil sulfate is

an imidazole fungicide (Group 3)

that inhibits sterol synthesis thus

affecting cell wall permeability. As a

consequence, PHILABUSTER® is a

fungicide with preventive, curative

and anti-sporulant activity.

Use Recommendations

• For optimal use of the product, it should be applied as soon as possible after harvest but ideally within 24

hours to be able to protect harvest wounds.

• Always make a premix of PHILABUSTER® by gradually diluting the product 5 times with water under constant

stirring. The obtained premix will offer a very stable treatment suspension.

• Ideally, the treatment water should be stirred all day long.

• PHILABUSTER® is not compatible with most of the disinfectants specially the one containing chlorine. In case of

incompatibility, the concentration of the disinfectant could be an influencing factor.

• PHILABUSTER® is generally compatible with other fungicides but mixing PHILABUSTER® with other fungicides is

only needed in specific cases because of the spectrum and level of efficacy of the product.

• Residues are also influenced by several factors including treatment time, pH and temperature of the treating

solution.

As citrus fruit is stored and/or transported all over the world, a long lasting activity is essential for a good

postharvest product in the citrus fruit segment. Fewer products are available to preserve citrus fruit from decay,

therefore it is essential that proper management practices are utilized when using the few remaining products.

Efficacy of PHILABUSTER®

PHILABUSTER® is a very effective product which can be applied through a variety of application methods such as

dip and drench applications but also the aqueous and wax spray applications. Each of these application methods

has its own level of treatment quality which will ultimately influence the effectiveness of the fungicide.

PHILABUSTER® has been developped as a tool for anti-resistance management offering two active ingredients with

different modes of action against the main pathogens in citrus.

Nevertheless it is advised to use the product in a sustainable way to preserve it on the long term. All products

must be applied at full dose rates to limit the risk of resistance. Low residues and under dosing can hasten the

development of resistance.

Janssen PMP provides sensitivity monitoring to track any on the resistance development in any of the pack houses.

With this tool, it is possible to pick up, in a very early stage, possible issues before they result in an insufficient

control under practical circumstances. Based on the results, timely efforts and adaptations of treatment schemes

and sanitation measurements can be made to preserve your fruit.

Please contact your service company for any further support.

Good Management Practices

Good management practices include sanitation, both in the orchard and in the packing house. Sanitation is the first

line of defense in decay and fungicide resistance management. A poor sanitation program will undo the positive

effects of any fungicide management program.

In the orchard

• Remove inoculum sources of orchard-related pathogens.

• Do not place bins on muddy orchard soil.

In the packinghouse

• Avoid build-up of inoculum in the drench water by adhering strictly to drench water change schedules.

• Sanitize water systems, packing lines, storage rooms, and bins.

Key use reasons for PHILABUSTER®

• Superior efficacy against green and

blue mold decay

• Long term activity

• Preventative, curative and anti-

sporulant effect

• Essential tool for resistance

management in the packing house

• Widespread establishment of MRLs for

Imazalil and Pyrimethanil

• Flexibility of use in aqueous and wax

applications

• Excellent Return on Investment
