Why you need Infinito

  • Highly effective against foliar, stem and tuber blight and protects new growth
  • Blocks every stage in the late blight life cycle with protectant, curative and anti-sporulant efficacy
  • Co-formulation of two active substances with unique modes of action for ‘stand-alone’ performance and resistance management

How does Infinito work?

Infinito is a co-formulation of fluopicolide and propamocarb; active substances which work hand in hand to protect every part of the potato plant – leaves, stems, tips and tubers – and attack the late blight pathogen at every stage of its life cycle. As a result it has premier league Euroblight ratings for effectiveness against foliar blight, tuber blight and anti-sporulant efficacy.

Fluopicolide is a strong protectant fungicide and has translaminar mobility. It works by disorganising the pathogen’s cell structure, disrupting the formation of spectrin like proteins, believed to play a vital role in maintaining the pathogen’s cytoskeleton stability. This novel mode of action is highly effective at all key stages in the life cycle. In particular, fluopicolide’s activity against motile zoospores is dramatic. Under the microscope, it is seen to halt their movement immediately on contact and in less than a minute they burst.

Propamocarb is also a strong protectant fungicide and has systemic mobility. It disrupts the formation of fungal cell walls by interfering with phospholipid and fatty acid synthesis. This mode of action attacks a number of stages in the life cycle and crucially pushes the pathogen into direct germination which limits spore production to a tenth of its potential.

With the highly aggressive blight strains now dominating, every opportunity must be taken to block the life cycle. Infinito is effective at all key stages: sporulation, zoospore and cyst formation, zoospore mobility, cyst germination and mycelial growth.

Activity on both direct and indirect germination of sporangia provides strong and reliable action against the disease, regardless of temperature. Its power to control mycelial growth also blocks the pathogen’s sexual reproduction route by preventing the mycelia of different mating types from meeting.

When and how to apply

Diseases controlled

When used as part of a full blight protection programme of correctly timed sprays, Infinito gives control of late blight of potatoes (Phytophthora infestans).

Infinito will protect tubers from the risk of late blight infection after harvest and reduce tuber blight incidence when used as part of a full blight protection programme from full canopy development to haulm desiccation.

Application

Applications must be made preventively as part of a blight control programme with regard to blight infection periods or local blight warnings. In the absence of any warnings, applications should commence when the crop meets along the row.

Apply Infinito only to dry foliage. Do not apply if rainfall or irrigation is imminent. Infinito is rainfast in 1 hour providing the spray has dried on the leaf.

Apply Infinito at 1.2 to 1.6 L/ha on a 7-10 day spray interval, depending on disease pressure. As disease pressure and the risk of late blight infection increases, the dose should be increased and the interval shortened. Irrigated crops should be treated as high risk.

Infinito may be applied at a shorter interval than indicated above should there be
an agronomic need as long as all other conditions of use are followed, particularly the maximum number of treatments, maximum total dose and the latest timing.

Infinito should be applied as a protectant treatment. Do not apply as a curative treatment when blight is present in the crop. When blight has become readily visible (1% leaf area destroyed), fungicides have little effect on subsequent development. Stop using Infinito under these conditions.

Varieties

Infinito may be used on all varieties of potato and crops grown for seed.

Planning blight programmes

In the fight against today’s blight strains Infinito is widely considered as a ‘must have’ in any blight strategy. To get the most from its foliar and tuber blight efficacy and anti- sporulant mobility it is best used through the stage of crop growth when the risk of foliar blight is high and/or when conditions are conducive to tuber infection. Generally this means from canopy compete onwards.

A sound strategy is to plan to incorporate sprays of Infinito in alternation with complimentary fungicides from canopy complete until complete haulm destruction (Diagram 14). Not all Infinito sprays need be aimed at high-risk periods. It has been recognised that tuber protection is optimised by building it up from shortly after tuber initiation.

This approach is far more effective than waiting until blight is active in the canopy and spores are being washed down to the soil below before introducing fungicides with tuber blight activity. Using Infinito from canopy complete onwards in this way will build in the strongest possible backbone of tuber protection.

undefined

To obtain the best protection against all strains of late blight use Infinito at 1.6 L/ha at 7-day spray intervals in programmes with fungicides from different chemical classes. Once the maximum dose of 6.4 L/ha per crop has been used up, switch to other products with tuber blight activity to complete the programme.

EAMU – broccoli/calabrese,  Brussels sprout,  cabbage,  cauliflower,  kale, collard

This Extension of Authorisation relates to the use of Infinito to control downy mildew (Peronospora spp.) on protected and outdoor broccoli / calabrese, Brussels sprouts, cabbage, cauliflower, kale and collards.

Applications should be made using conventional hydraulic spray equipment at a maximum application rate of 1.6 litres product / ha in a minimum water volume of 200 litres water/ha. Applications made at BBCH 40 or later must use a minimum water volume of 500 litres water/ha.

Only one application is to be made indoor (greenhouse) prior to transplanting, with a latest timing of application of BBCH 14 (before 4 true leaves).

Only one application is to be made outdoors between BBCH 20 and BBCH 49, and should be applied no later than 14 days before harvest.

Applications must only be made between 1 April and 31 October. Growers are advised to test a small area of crop prior to wider commercial use.

Resistance Management

To reduce the incidence of resistance developing, Infinito should be used in single or block applications in alternation with fungicides from a different cross-resistance group. For the latest guidelines refer to the FRAG-UK website where the 2018 publication 'Fungicide resistance management in potato late blight' is available to download.

Certain diseases may develop resistance to Bayer's products. Since such circumstances are beyond our control, Bayer can accept no liability for any loss or damage whatsoever.
