How to maximise the efficacy of fungicide programmes with the inclusion of ARIZONA (500g/l folpet)
A carefully considered programme of fungicides will therefore be needed to ensure those cereals which have been drilled and established successfully go on to achieve their true yield and quality potential.
PROTECTION, NOT CURE
The critical factor in ensuring all cereal crops receive adequate protection from diseases such as septoria, rusts, ramularia, net blotch and rhynchosporium is to ensure that a suitable fungicide programme starts as early as possible, preferably before infections take hold.
With several single site fungicides showing signs of reduced efficacy (particularly SDHI chemistry which continues to be eroded by increasing levels of disease resistance), it is important to limit the exposure of at-risk active ingredients. This is best achieved by using a range of fungicides throughout the season, and by partnering different active ingredients with products of an alternative mode of action.
For example, to improve disease control efficacy and protect the current armoury of single site fungicides, a multi-site fungicide such as folpet should be included at key stages in the crop protection programme.
WHEN TO USE ARIZONA IN WHEAT
T1 is a key timing for the control of septoria in wheat. Using ARIZONA at this timing will provide a positive yield response and reliable return on investment.
For the best results, a second application at T2 will further enhance disease control and protect partner chemistries.
In higher risk situations (e.g. a susceptible variety facing high disease pressure), ARIZONA should also be considered at T0 to provide early season protection before diseases take hold.
WHEN TO USE ARIZONA IN BARLEY
In barley, T2 (GS39-49) is the key timing in any scenario, especially for the control of ramularia.
ARIZONA can also be used at T1 when its inclusion will provide added protection against rhynchosporium and net blotch, or at T0 if the season dictates that early protection is required.
To achieve the best control of these diseases, ARIZONA should be included at T1 and T2. Including ARIZONA helps maintain green leaf throughout the canopy.
FOLPET: MULTI-SITE EFFICACY AND VALUE
ARIZONA® (folpet 500 g/l) is a unique multi-site fungicide that provides valuable additional protection against key diseases in wheat and barley. It also delivers a reliable return on investment through enhanced disease control, as well as safeguarding the efficacy of partner products as part of an anti-resistance strategy.
Including ARIZONA (folpet 500 g/l) as part of a programme of fungicides gives the following benefits:
- ARIZONA enhances disease control by providing additional activity against septoria in wheat, and ramularia, net blotch and rhynchosporium in barley. ARIZONA also provides a useful reduction of yellow and brown rusts, as well as intrinsic activity against mildew.
- ARIZONA delivers a reliable return on investment by extending green leaf area duration. This directly translates into higher yields and enhanced crop quality, with every £1 spent on ARIZONA providing a £4 return on investment.
- ARIZONA’s unique folpet multi-site mode of action makes it the only fungicide which has been proven to extend the effective lifetime of at-risk fungicides by delaying the development of resistance.
