Contractorsand machinery manufacturers are responding to the move in the market towardsAvadex Excel 15G (tri-allate) as part of a weed control programme and aremaking the necessary investments to satisfy this demand.
ContractorRichard Lapage of R&H Contract Services, based in Framlingham, says thereis a huge demand for this herbicide this year from both growers andagronomists. Not just for black-grassbut also for wild-oats and other grass-weeds. I have repeat customers who saythey have hundreds, not tens, of hectares to control this year. For the firsttime this spring we were also asked to apply Avadex Granules to spring barleyand sugar beet, he continued.
Inresponse to high grower demand, Richard Lapage and his business partnerJonathan Tunmore have invested over 50,000 in a Mercedes Benz Forward ControlUnimog with 32 metre aluminium Pommier booms, which has two Horstine Twin Airpositive displacement applicators mounted on it. This is a bespoke piece of kit. But as thisherbicide needs to be applied soon after drilling, the small window ofopportunity requires a system that can cover the ground quickly, but stillapply granules accurately. It has a maximum 32 metre width, but we will fit inwith tramlines at 30, 24, 18 and 12 metres. The applicators apply the AvadexGranules accurately as it has 32 outlets at one metre spacings, each fed by itsown individual metering rotor.
Richardand Jonathan hope to apply 5000 hectares of Avadex Granules this autumn, whichis well up on previous years. Ourcontracting services cover Suffolk, Norfolk, Essex and Cambridgeshire. With thenew kit we will be able to treat more hectares and be certain of accurateapplication.
JoeAllen of Horstine Farmery liaised with R&H Contract Services to create theexact system to suit his business and customers needs. Busy contractors suchas R&H Contract Services want larger machines that can cover more groundmore quickly.
Weare also supplying many more smaller, light weight systems, the TMA4, togrowers who want to apply Avadex Granules themselves. In fact we planned tobuild 20 applicators and nearly half of them were sold before we evenadvertised the product! Certainly the demand for this herbicide and henceapplicators and contracting services is very much higher this year, says Joe
Heexplains that, as the Avadex is applied after drilling, you need an applicatorthat can tread lightly so you can get onto the land when required. The TMA4 has this light foot print. Growerslike the accuracy of this applicator it offers individual metering to eachdistribution outlet for guaranteed accurate application across the full 12metre width. Metering is controlled using an automatic rate controller, whilstthe fan is hydraulically powered rather than PTO driven. It also can shut offat the headlands to avoid over- lapping extra product. When applying Avadex youdont want to overdose or under dose, with black-grass being such a difficultand competitive weed.
Dr.Dominic Lamb of Gowan reports that there is already an unprecedented highdemand for the use of the residual herbicide Avadex this autumn. Many more growers want to use it as the essentialstarting point of their herbicide programme. This is because it fulfils a keyrole in the control of difficult-to-control grass-weeds such as black-grass,annual meadow-grass and wild-oats as well as some common broad-leaved weedsincluding cleavers, charlock, chickweed, mayweeds and poppy.
Inthe last couple of years many farmers have used a contractor or have investedin their own applicators to apply Avadex Granules, as they are keen tointegrate this valuable active ingredient into their weed control programme in winterand spring crops, he says.
Dominicsays that Avadex is an essential part of any weed control programme and is bestpositioned as the starter herbicide. Applied pre-emergence at a dose rate of 15 kgs/ha towell-prepared moist seedbeds, Avadex de-waxes and sensitises black-grass andother weeds, boosting the overall efficacy of the herbicide programme. It canthen be followed by a flufenacet-containing herbicide such as Crystal(flufenacet + pendimethalin). Tri-allate is known to work in a differentway to most other cereal graminicides and is once again finding a key positionin many weed control programmes, its robust performance proven with over 50years of use in the UK.
AvadexExcel 15G contains 15% w/w tri-allate, formulated as a granule. It isrecommended on winter wheat, winter barley, durum wheat, triticale, winter rye,winter field beans, spring barley, peas, spring field beans, forage legumes,sugar beet, fodder beet, mangel and red beet. It controls wild-oats, volunteer(tame) oats and moderate populations of Italian rye-grass, annual meadow-grassand black-grass.
Applied pre-emergence of weeds, usefulcontrol of annual broad-leaved weeds including cleavers,charlock, chickweed, common poppy, field pansy, field speedwell, forget-me-not,fumitory, ivy leaved speedwell, mayweed spp and red dead-nettle is obtained. It is applied at a dose rate of 15kg/ha, with one application per crop. It is packed in a 1ha pack (15 kg).
