Insignia Turf Fungicide 250g

Insignia®

MAPP 19403

Insignia® is a strobilurin-based local penetrant fungicide available in a water dispersible granule formulation.

Authorised for use on managed amenity turf, Insignia® contains, 200 g/l (20%) pyraclostrobin providing both protective and curative action.

Insignia® is a local penetrant fungicide for the control of red thread (Laetisaria fuciformis), microdochium patch (Microdochium nivale), and dollar spot (Sclerotinia homoeocarpa) when turf is actively growing.

Active Substance

Insignia® contains pyraclostrobin an active substance from the strobilurin family of fungicides.

Mode of Action

Mode of action describes how a fungicide impacts a fungus, The Fungicide Resistance Action Committee (FRAC) currently recognises 13 classifications with pyraclostrobin belonging to Mode of Action Code C: Respiration.

Target site of action and group name

Like many fungicides, pyraclostrobin affects a single site within the fungi; specifically, complex III of the mitochondrial electron transport chain. By inhibiting this pathway, pyraclostrobin blocks the fungal pathogen’s ability to respire and produce energy through the transfer of electrons within its cells. Fungicides which affect this process are assigned the code C3 and the name Quinone outside Inhibitors (QoI).

FRAC code

As a QoI fungicide pyraclostrobin falls within Fungicide Resistance Action Committee (FRAC) code 11 for resistance management.

Phytomobility and Movement Through the Plant

Phytomobility describes how an active substance such as pyraclostrobin, penetrates and moves within a plant after it has been deposited onto and then absorbed into underlying tissues.

Local penetrant

Pyraclostrobin is a local penetrant fungicide which means once applied, the active substance will remain concentrated close to the site of application.

Translaminar movement

Movement of the active substance will be through the plant leaf from one side to the other. This type of movement through the plant is described as translaminar movement. The word trans being derived from the Latin prefix for ‘through’ or ‘across’, with lamina arising from the use in botany to describe a leaf. Translaminar movement may also be referred to as mesostemic.

Apoplastic cell movement

The movement through the leaf occurs around the cell wall structure and through gaps between the underlying plant cells. Eventually the pyraclostrobin makes it to the opposite side from its original application. This type of movement is classified as apoplastic and occurs in one of two ways. Either within cell walls or between intercellular spaces.

Lipophilic

The pyraclostrobin within Insignia® is lipophilic, which means it tends to combine with lipids such as fats, oils and waxes. Consequently, once applied most of the pyraclostrobin is initially held on or within the outermost area of the leaf surface, the waxy cuticle. Following movement through the leaf it will also bind to the waxy cuticle on the opposite side of the leaf.

Advantages of a Local Penetrant Fungicide

The pyraclostrobin within Insignia® is a local penetrant fungicide, with translaminar movement through the plant and apoplastic movement between plant cells. These characteristics provide Insignia® with key advantages for a turf manager seeking to protect their grass plant from fungal pathogens.

Protection inside the plant

Because a local penetrant translaminar fungicide, such as pyraclostrobin, passes from one side of the leaf to the other, fungitoxic concentrations of the substance within the leaf restrict growth of fungal pathogens inside the plant.

Protection on both sides

Translaminar movement through the leaf builds a concentration of the active substance on the opposite side of the leaf. Supressing existing infections beneath the site of fungicide application.

Protection over time

Pyraclostrobin’s affinity for lipids in the waxy cuticle, allows deposits of the active substance which are accumulated on both side of the leaf blade surface to be retained over time. These accumulated deposits serve as a weather resistant reservoir, releasing active substance both across the leaf surface and into deeper tissues over several weeks. Thereby protecting leaves and roots against new infections.

Stages of Control

Pyraclostrobin targets more stages of a fungal pathogen’s life cycle than other strobilurin fungicides, such as azoxystrobin.

Fungicide Performance

Insignia® application

Obtaining the best results from any Plant Protection Product is enhanced by skilled application, with well calibrated equipment and correct nozzles choices. It is also important to consider the prevailing climate conditions and current stage of disease expression.

The pyraclostrobin within Insignia® performs consistently at cooler temperatures

• Insignia® is suitable for application all year round in temperatures between 5-25°C
• Insignia® is rain fast within 1 hour of application

The Intrinsic® effect – strengthening turf from the inside out

As part of the Intrinsic® family of BASF fungicides, Insignia® delivers additional benefits to the grass plant over and above direct disease control.

• As a fungicide, the pyraclostrobin within Insignia® severely inhibits mitochondrial respiration inside the cells of pathogenic fungi. This prevents the breakdown of carbon that is required for fungi to produce the energy they need to function.
• In addition to the fungicidal properties, pyraclostrobin actively works beneficially within the grass plant, whereby a minor inhibition of mitochondrial respiration triggers a cascade of positive events which lead to plant health benefits.

These benefits are an intrinsic aspect of the way in which pyraclostrobin and Insignia® positively impact the reorganisation of metabolic and physiological plant processes.

In addition to directly controlling fungal pathogens, the Intrinsic® effect from Insignia® helps plants to:

• Resist disease attacks
• Withstand abiotic environmental and physical stress
• Grow more efficiently
