Novall is a residual herbicide that can be used on all varieties of winter-sown oilseed rape for the control of cleavers and a range of other broad-leaved and grass weeds.

 

When Novall is applied pre-emergence, it is important for crop safety to ensure physical separation of the herbicide from the seed.

This is achieved by ensuring that the seed is well covered with soil to a depth of 15 mm.

With direct-drilled crops, harrow across the slits to cover the seed before spraying.

Loose or puffy seedbeds must be consolidated before treatment.

Seedbeds should be moist, firm and free from clods.

Novall is suitable for use on all soil types as defined by Soil Texture (85) System, except sands and very light soils and soils containing more than 10% organic matter.

On brashy and stony soils, Novall may cause some reduction in crop vigour and/or plant stand, due to the chemical moving down to the root zone too quickly.

Do not apply Novall to soils with a compaction layer or to poorly drained soils, since damage can occur under waterlogged conditions.

If Novall is applied onto a dry soil surface it will only be effective after rain has occurred.

To reduce the risk of movement of Novall to water:

a. On clay soils, create a fine, consolidated seedbed to slow the downward movement of water.

b. Do not apply Novall to dry soil. Moist soils have fewer and smaller cracks.

c. Do not apply Novall if heavy rain is forecast, wait until after the event.

A reduction in crop vigour, weed control and possibly plant stand may occur if excessive rain falls shortly after application, particularly on the lighter soils. Where a crop check has occurred, this normally grows out after a few weeks and yields are normally unaffected.

Do not use on broadcast crops.

Do not overlap spray swaths, particularly on headlands.

Do not treat crops which are suffering from wilting, pests or diseases.

Under frosty conditions a transient scorch may occur.

Avoid spray drift onto neighbouring crops.

Strains of some annual grasses (e.g. black-grass, wild-oats, and Italian rye-grass) have developed resistance to herbicides which may lead to poor control. A strategy for preventing and managing such resistance should be adopted. Guidelines have been produced by the Weed Resistance Action Group and copies are available from the HGCA, CPA, your distributor, crop adviser or product manufacturer.

 

Novall can be used on all varieties of winter-sown oilseed rape Novall may be applied pre- or post-emergence of the crop but for maximum activity application must be pre- emergence of the weeds.

Pre-crop emergence applications should be made on medium and heavy soils only (as defined by the ADAS Soil Texture (85) system). Application should be made before the crop seed chits, which in warm moist soils may occur within 48 hours of drilling.

Seedbeds should be moist, firm and free from clods, but also see Restrictions/Warnings section.

DO NOT USE ON BROADCAST CROPS.

DO NOT USE NOVALL pre-crop emergence when any of the following conditions apply:

When heavy rain is forecast

Dry cloddy seedbeds

Late drilled crops - as a guide these are crops drilled later than the first week in September in Northern

England and Scotland and later than mid September in the rest of the UK.

Stony soils, i.e. stones, flints or chalk, readily visible on the soil surface.

Post-crop emergence applications can be made on light, medium and heavy soils (as defined by the ADAS Soil Texture (85) system). Application can be made from when the majority of the crop has two fully expanded cotyledons until before the end of January.

Post-emergence application of Novall is recommended if:

Seedbed conditions are not ideal for pre-emergence use

The seed is not covered with 15 mm of soil (as with broadcast crops)

Novall could not be applied before the seed chits Light soils, or all recommended soils which are stony, brashy or gravelly, are to be treated particularly if heavy rainfall has been forecast for the period following drilling Late drilled crops are to be treated.

 

Any crop can follow normally harvested winter oilseed rape treated with Novall. Ploughing is not essential before sowing a following cereal crop, but is required for other crops.

In the event of crop failure in the autumn or winter, then only the crops listed below can be drilled after the use of Novall:

Re-drilling the following spring – spring barley and potatoes may be sown after ploughing.

Apply 2.5 litres/hectare Novall.

Apply as a MEDIUM spray, as defined by BCPC.

Novall should be applied in a minimum water volume of 220 litres/ hectare.

Do not use filters finer than 50 mesh.

SHAKE WELL BEFORE USE.

Half fill the spray tank with clean water and start the agitation.

Pour in the required amount of Novall.

Add the remainder of the water and continue agitation until spraying is completed.

Rinse empty containers thoroughly and add rinsings to the spray tank.

Do not overlap spray swaths, particularly on headlands.

Avoid spray drift onto neighbouring crops.

WASH EQUIPMENT thoroughly immediately after use.

Fill the tank with clean water and leave overnight.

Spray out before storage or using other products.
