(S = Susceptible MS = Moderately susceptible * = Approved formulations ** = Where metabolic resistant black-grass has been identified and there are more than 100 plants/m2 . LEXUS SX may be applied at 40 g/ha as part of a herbicide programme which must include a pre-emergence treatment. Under these circumstances treatment must commence as soon as possible when the black-grass has no more than 1-2 leaves. When used as part of such a programme, 40 g product/ha may give improved control compared to 20 g product/ha. (1) = Deep germinating Volunteer Oilseed Rape may not be controlled (2) = Heavy infestations may require re-treatment in the Spring with an approved Black-grass herbicide (3) = Useful control of Autumn germinating Wild-oats has been observed. Heavy infestations, or where significant flushes occur in the Spring, may require a Spring application of an Approved Wild-oat herbicide. (4) Regrowth of Chickweed may occur where residual activity is reduced by excessive rainfall warm soils and/or very dry soil conditions.)

 

Strains of some annual grasses (eg Black-grass, Wild-Oats, and Italian Ryegrass) 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. Populations of black-grass and Italian ryegrass with high levels of enhanced metabolism resistance will not be fully controlled.

Key elements of the resistance management strategy for PDM 330 EC: - Always follow WRAG guidelines for preventing and managing herbicide resistant weeds. - Maximise the use of cultural control measures wherever possible (e.g. crop rotation, ploughing, stale seedbeds, delayed drilling, etc). - Use tank mixes or sequences of effective herbicides with different modes of action within individual crops, or successive crops. - For the control of herbicide resistant grassweeds, always use PDM 330 EC in tank mix or sequence with other effective graminicides with different modes of action. - Apply pre-emergence of weeds wherever possible. If applications are delayed, apply post-emergence products/mixtures to small, actively growing weeds, especially where high levels of resistance are suspected and to reduce the risk of resistance development. - Monitor fields regularly and investigate the reasons for any poor control.

 

PDM 330 EC is recommended for use on all varieties of approved crops on any mineral soil except where indicated in the table below.

Product: PDM 330 EC + Atlantis WG + Biopowe

Rate: 4.0 l/ha + 400 g/ha + 0.5%

Water volume: 200 litres/hectare

Timing: Apply post-emergence from 2 leaves on the crop. Apply to young, actively growing weeds. Optimum timing for Black-grass control is 1-3 leaves of the Black-grass.

Notes:For optimum activity, apply when weather conditions promote active weed growth. Do not apply to crops suffering from stress, which may be caused for example by pests, disease, water logging, poor seedbed conditions or previous chemical treatment. Under certain climatic, soil and crop conditions some slight chlorosis and stunting of the crop may occur. If frost is likely, avoid spraying non frost-hardened crops. Avoid spraying during periods of prolonged or severe frost. Control may be reduced if rain falls within 2 hours of application. Thoroughly clean all spray equipment with a proprietary sprayer cleaner immediately after spraying to avoid subsequent damage to crops other than cereals.

Rate: 4.0 l/ha

Water volume: 100 to 200 litres/hectare.

Timing: Pre-emergence of the crop. Apply PDM 330 EC as soon as possible after drilling and before emergence. Due to risk of dry soils, do not apply PDM 330 EC alone after the end of March (mid April in Scotland) unless rainfall is imminent.

Seed depth: Seed must be covered with a MINIMUM of 3.2cm of settled soil.

 

Product: PDM 330 EC

Rate :4.0 l/ha

Water volume: 100 to 200 litres/hectare.

Timing: Pre-emergence of the crop. Apply PDM 330 EC as soon as possible after sowing and final seedbed preparation. Do not apply if the plumule is less than 13mm from the soil surface. Due to risk of dry soils, do not apply PDM 330 EC alone after the end of March (mid April in Scotland) unless rainfall is imminent. Soil types All mineral soils except gravelly soils

Seed depth: Seed must be covered with a MINIMUM of 2.5cm of settled soil.

 

Products: PDM 330 EC + Sencorex WG

Rate: 4.0 l/ha + 0.5 kg/ha In dry conditions apply a PDM 330 EC – Sencorex WG sequence.

Water volume: 200 litres/hectare.

Timing: Pre-emergence of the crop. Apply as soon as possible after planting and final ridging up. Loose structured ridges must be allowed time for settlement before application. Do not apply later than 7 days before emergence.

Soil types: Do not use on Sands (S), Gravelly or Stony soils.

Variety :Read the Sencorex WG label carefully, particularly with regard to varietal restrictions.

Application: PDM 330 EC should be applied in a minimum of 200 litres of water/ha.

Notes: Best weed control will be achieved with settled well-rounded ridges with few clods. If re-ridging is necessary, delay application until after the final ridging is completed. Slight distortion and discolouration of the initial shoots may occur if very heavy rain falls after application but before emergence, particularly to crops grown on very light soils. This is quickly outgrown and subsequent growth is unaffected. Read the Sencorex WG label carefully, particularly with regard to following crop restrictions.

 

Product: PDM 330 EC

Rate: 4.0 l/ha

Water volume: 100 to 200 litres/hectare.

Timing: Apply as soon as possible after sowing and final seedbed cultivation, before crop and weed emergence.

Seedbed: Consolidate seedbeds after drilling to provide a firm level soil. Seed should be drilled so that after seedbed consolidation it is covered by a minimum of 2.5cm of settled soil

 

Product: PDM 330 EC

Rate: 4.5 l/ha

Water volume: 100 to 200 litres/hectare.

Timing: Forage and grain maize: before 4th leaf of the crop. Maize grown under temporary plastic mulch: pre-emergence

Notes: Do not use on Sweetcorn or Maize grown for seed. Seed must be covered by a minimum of 5cm of settled soil. The use of PDM 330 EC may affect the full development of crown roots which function only to anchor the plant. This has no effect on the yield of maize. If application is followed by a period of dry conditions or in situations where very heavy populations occur, a sequence of PDM 330 EC and a product applied post-emergence may be necessary.

 

 

 Carrots and Parsnips

Product: PDM 330 EC

Rate :4.0 l/ha

Water volume:100 to 200 litres/hectare.

Seed depth: Seed should be covered with a minimum of 2.5cm of settled soil.

Application: When transplanting, care must be taken not to introduce treated soil into the root zone.

Soil types: PDM 330 EC is not recommended for use on onions or leeks grown on sands (CS, S, FS, LCS), very light soils (LS, LFS, CSL), as crop damage may result. PDM 330 EC is not recommended for use on onions or leeks grown on fen soils or other soils containing in excess of 10% organic matter, as weed control may be reduced.

Notes: If weeds are present, these can be controlled by applying PDM 330 EC in tank mix with a recommended contact herbicide. Read tank mix partner label carefully for restrictions on transplanted multi-seeded onions or leeks.

 

Product: PDM 330 EC

Rate: 4.0 l/ha

Water volume :100 to 200 litres/hectare.

Timing: Maiden Beds - runners should be planted so that roots are well covered. - good consolidation of the plantbed is necessary for good weed control. - PDM 330 EC should be applied to dormant newly planted runners in the autumn or early spring immediately after planting and prior to weed emergence. - if runners are likely to be slow in establishing due to stress conditions, such as drought, at the time of planting, the application of PDM 330 EC should be delayed until plants have established and are free of stress. - application made after runners have started growing away may reduce the initial vigour of new foliage but this will be rapidly outgrown. - do not apply PDM 330 EC before October to beds newly planted with cold-stored runner or beds newly planted in late summer. - pre-planting application of PDM 330 EC is not recommended. Established beds - apply PDM330 EC to weed free soil from autumn to early spring during the dormant period of the crop. - PDM 330 EC applied after the end of March or after the emergence of flower trusses in the spring may affect crop yield, particularly if conditions adverse to vigorous plant growth follow application. - do not apply PDM 330 EC during the flower initiation period (immediately post-harvest to mid-September).

Notes: Leaf growth of strawberries may be checked following applications of PDM 330 EC in the spring but, in extensive experimentation, this has been shown not to affect yield. Do NOT use PDM 330 EC on protected crops or crops grown in green houses.

Product: PDM 330 EC

Rate: 4.0 l/ha

Water volume :100 to 200 litres/hectare.

Timing: Apply PDM 330 EC after final cultivation to weed-free soil from autumn to early spring. PDM 330 EC is not recommended for use after the end of March unless adequate soil moisture is present as some soil moisture present is essential for the chemical to be activated. Do not apply to autumn fruiting raspberries. Newly planted crops: - PDM 330 EC should be applied immediately after planting. - a light ridging along the cane row before application is recommended to ensure roots are well covered. - PDM 330 EC should be applied well before the emergence of the new canes. Established crops: - PDM 330 EC should be applied as soon as the canes have been cut out and tied, but before bud burst.

Tank mixes: If emerged weeds are present at application, PDM 330 EC may be applied as a directed spray in tank mix with a recommended approved contact herbicide.
