Keeping the tip of nozzles at the design height of 50 cm above the weeds gets their best performance, and maximises the deposition of the herbicide on the foliage. It also likes potato fields, vegetable patches and other similar culturally-influenced land. Residue spreading and shallow stale seedbed cultivation by raking combined with surface rolling, or shallow discing/rolling is effective to manage residues, control slugs and create the best conditions for weed stimulation. If sprays are delayed until the crop and weed are established then control of larger weed plants becomes more difficult and the crops will have already have suffered some yield loss as a result of the weed competition.

A narrow angled fan jet with an optimised trajectory has proven to be the best compromise so far between optimum deposition, while minimising spray drift. The faster the forward speed of the sprayer, the smaller the proportion of the spray will cover the rear aspect of the clods, so a forward speed of no more than 12 km/h is recommended. Scentless mayweed is shallow germinating because it requires repeated diurnal exposure to light over a period of days to stimulate germination. Please contact us if you require more. (ii) Use disc openers or straight discs ahead of tine openers. Widespread, scentless mayweed especially. Germination is also stimulated by light. The best strategy for a single year fallow would be to leave the stubble in the autumn undisturbed to maximise predation, use shallow cultivations to encourage germination and control weeds germinating in the major autumn and late spring emergence flushes.

The dilemma is that tillage will reduce predation and germination of fresh seeds but will stimulate old seeds to germinate, so knowledge of the position and number of seeds in the profile is vital. Maintain seed bank horizons by controlled surface disturbance of all operations. Scentless mayweed is very variable in size and habit. To get the best control, all of these products should be used either pre or very early post-emergence of the weeds. Cultivations will enhance the emergence of buried (old) seeds by exposing them to light. Ultimate cultivation depth to be just greater than the drilling depth for the following crop, ideally ≤ 5cm. Early post-emergence sprays are bad for drift, because of the lack of crop. Effective burial by: (i) Suitably narrow furrow width (30/35cm on heavier soils) and share width < furrow width, (iii) Appropriately set skimmers post plough pressing to close the surface. Dense populations can smother and severely restrict crop growth so it needs to be controlled.
