Getting the best from Betanal maxxPro

Betanal maxxPro brings the ultimate flexibilty to target optimal timings and spraying hours. Used in a low-volume overall spray programme, well-timed applications of Betanal maxxPro from the cotyledon stage of the crop will control annual broad-leaved weeds up to, and including, the fully expanded cotyledon stage.  Apply the first spray at 1.25 L/ha when weeds are at cotyledon stage and increase to 1.5 L/ha for second and subsequent sprays to the crop at or beyond two true leaf stage.

Always apply as a FINE quality spray in a water volume of 80 – 200 L/ha.

Important things to remember

  • When tank-mixing always fully disperse WG and WP products before adding Betanal maxxPro
  • Certain tank-mixes may require additional adjuvant oil for improved weed control in difficult circumstances or when recommended for partner products
  • Do not use adjuvant oil during periods of rapid growth or when crops are under stress
  • Application to crops suffering from stress may lead to a check in growth from which the crop may not recover or, in extreme cases, lead to crop loss

What is Betanal maxxPro?

Betanal maxxPro is a broad-spectrum post-emergence contact/residual herbicide, which controls a wide range of annual broad-leaved weeds and annual meadow-grass in sugar beet, fodder beet and mangels.

Betanal maxxPro is recommended for low volume overall spraying in a planned spray programme and can follow an approved pre-emergence herbicide and/or approved post-emergence herbicide treatment(s) used at recommended low doses for programmes. It may also be used in sequence with grass weed killers.Refer to graminicide product literature for recommended intervals.

Betanal maxxPro acts mainly by contact action but will, in a planned programme and in moist conditions, provide residual control of some later germinating weeds.

Betanal maxxPro and the flexible strategy for weed control

The flexible strategy was developed by Broom's Barn to bring greater flexibility in weed control and increase spraying capacity across the farm as a whole. It widens the spraying window for weed control by enabling the application of robust, broad-spectrum treatments to weeds at the early true leaves stage. It also provides the opportunity to deploy the same tank-mix across a number of fields and allows selection of spray days with optimum conditions for herbicide activity to avoid the risk of crop damage.

undefined

Initially the flexible strategy was based on Bayer's three-way co-formulation of desmedipham, phenmedipham and ethofumesate - mixed with an appropriate residual herbicide, usually metamitron or lenacil. Today it is based on Betanal maxxPro.

The combination of its advanced formulation technology and desmedipham component makes this product the most robust on the market. Not only does it give good, broad-spectrum weed control under good growing conditions - warm and moist - but equally when conditions are highly challenging to herbicide activity - dry and/or cool - which has been a common feature of recent weed control seasons in the UK.

As a result, the flexible strategy enables growers to achieve effective broad-spectrum control from two to three post-emergence applications.

The best weed control strategy for many will be the one that brings the flexibility to balance spraying capacity with workload. This is why the current trend is towards the flexible strategy.This is not just down to the need to reduce workload but also for the flexibility it brings to work around the weather and maintain good weed control even when delayed.

How does Betanal maxxPro work?

The key to Betanal maxxPro's performance is its innovative and patented Double-A Technology combining an advanced formulation technology and a unique activation technology.

The advanced formulation technology combines state-of-the-art solvents, emulsifiers and wetting agents in an OD (oil dispersion) formulation. As illustrated by the fluorescence photographs below this ensures even distribution of the active ingredients to optimise spreading and coverage of weeds’ leaf surfaces. By comparison the spray distribution from a generic SC formulation with adjuvant is clearly patchy.

Betanal leaf distribution

The result is faster and more reliable uptake of the active ingredients by weeds compared to a standard 3-way EC formualation without Double-A technology.

The other half of the Double-A Technology breakthrough is an activation technology based on a micro-rate of lenacil that significantly enhances the herbicidal performance of the active ingredients desmedipham, phenmedipham and ethofumesate.

Betanal ingredient penetration

The weed plant's stomato regulation is blocked shortly after the herbicide is applied. This has a two-fold effect - increased transpiration and a higher electro transport rate - which can be seen by the resulting reduction in leaf surface temperature from Betanal maxxPro. The impact of both effects is faster and more powerful weed control.

Betenals activation on surface temperature of weeds

Working together, the advanced formulation and activation technologies drive Betanal maxxPro's weed control performance, delivering broader spectrum control and a faster kill of more difficult weeds such as annual mercury, knotgrass, common orache and polygonums.

When and how to apply

Weeds controlled

The recommended timing of application is fully expanded cotyledon stage of the largest weed present and this should be followed wherever possible. The weed growth stage given below from the product label is for an occasional larger weed, which will usually be controlled from a full programme of Betanal maxxPro sprays.

 

Weeds killed up to 6 expanded true leaves

  • Common field-speedwell
  • Fat-hen
  • Wild Radish, (Runch)

 

Weeds killed up to 4 expanded true leaves

  • Annual meadow-grass
  • Black-bindweed
  • Common fumitory
  • Field pansy
  • Field penny-cress
  • Ivy-leaved speedwell

 

Weeds killed up to 2 expanded true leaves

  • Black nightshade
  • Corn marigold
  • Groundsel
  • Henbit dead-nettle
  • Knotgrass
  • Pale persicaria
  • Red dead-nettle
  • Redshank
  • Scarlet pimpernel
  • Small nettle

 

Weeds killed at cotyledon stage

  • Bugloss
  • Charlock
  • Common orache
  • Volunteer oilseed rape
  • Crane’s-bill (Qualified minor use recommendation)
  • Corn spurrey (Qualified minor use recommendation)

 

Other weeds controlled

  • Cleavers - killed up to 5 cm across or high.
  • Common chickweed - killed up to 10 cm across or high.
  • Mayweed - severe check or kill up to 2.5 cm across or high.

 

 

Application

All commercially grown varieties of sugar beet, fodder beet and mangels may be treated with Betanal maxxPro.
A programme of Betanal maxxPro low volume treatments should be applied as follows:

*Refer to summary of recommendations in document library for details of recommended mixes.

 

Where a pre-emergence treatment has been applied as
a band spray, it will be necessary to time the first post-emergence Betanal maxxPro treatment according to the size of weeds present between the rows where there is no pre-emergence effect.

 

A single application of Betanal maxxPro is seldom sufficient to achieve season long weed control.
Susceptible weeds may not all be killed by the first treatment. They will usually be checked and then controlled by later applications. Further Betanal maxxPro sprays should be applied as each new flush of weeds reaches the cotyledon stage.
Successful results from a programme are achieved by applying each spray when the previous one is still showing an effect on the weeds, but a minimum of 5 days must elapse between treatments.

 

Betanal maxxPro may be used on all soil types. On soils with more than 5% organic matter content residual activity may be reduced.

 

Succeeding crops

Beet crops may be sown at any time after the use of Betanal maxxPro. Any other crop may be sown 3 months after using Betanal maxxPro. Mouldboard ploughing to a minimum depth of 15 cm should precede preparation of a new seedbed.

 

Crop Tolerance

When used as recommended, Betanal maxxPro exhibits good safety to beet.

However, several factors may affect the crop tolerance and performance of Betanal maxxPro especially when used in mixtures. Some transient crop effects may occur soon after application but when the crop is under stress, application of Betanal maxxPro can lead to crop check from which it may not fully recover. In extreme cases some loss of crop may occur.

Application of Betanal maxxPro or Betanal maxxPro mixtures is not recommended when the crop is suffering from stress. Stress can be caused by a number of circumstances, the most important of which are as follows:

 

Use after other Herbicides

Most beet crops are treated with more than one herbicide. In these circumstances it is not always possible to predict the interactions, which may occur, and the effects of stresses in such conditions may be more severe.

 

Manganese Deficiency

If a crop is suffering from manganese deficiency it may be checked by Betanal maxxPro. To avoid crop check, manganese should ideally be applied to the crop first.

 

Lime Deficiency

Crops suffering from lime deficiency may be checked when sprayed with Betanal maxxPro. Growers should ensure that the lime status of the soil is satisfactory before drilling.

 

High Temperatures

When the temperature is, or is likely to be, above 21°C (70°F) on the day of spraying, application of Betanal maxxPro should be made after 5 pm otherwise crop check may occur.

If crops are subjected to substantial day to night temperature changes shortly before or after spraying, a check may occur from which the crop may not fully recover.

 

Frost

Crops sprayed with Betanal maxxPro and subjected to frost within seven days may be checked such that they may not fully recover.

 

High Light Intensity

Where the crop is already under stress, and Betanal maxxPro is sprayed in conditions of high light intensity, the crop may suffer a check from which it may not fully recover.

 

Wind

Strong winds can damage crops by physical buffeting and contingent damage can arise from blown soil particles. When wind damage has occurred, delay application of Betanal maxxPro until the crop has recovered.

 

Insect Attack

If insects damage the crop, e.g. mangel fly, pygmy mangel beetle or flea beetle, Betanal maxxPro may cause a check from which the crop may not fully recover.
