NEW LEYS - Protect your reseeding investment

Reseeds can come under pressure from attack by insect pests and competition from weeds.  Let Dow AgroSciences help protect your investment in new reseeds.

Once sown it is important to regularly inspect reseeds for signs of pests such as Frit fly and Leatherjackets, and also to correctly time herbicide applications where competitive weeds, such as chickweed and docks, are a problem.  Chickweed is one of the most competitive weeds with young grass.  Control of invasive annuals and, more importantly perennials, before they establish a large tap root, saves both yield and money in the long term.

Pastor* applied at 2.0 L/ha in 200 litres of water offers cost effective control of the key perennial weeds plus a wide range of annual weeds.  Applied from when the grass has at least 3 true leaves, Pastor is proven to be among the safest herbicide option for newly sown leys.

New leys can also succumb to attack from insect pests such as Frit fly.  Damage is caused by larvae tunneling into stems, leading to deadheart symptoms.  Frit fly larvae are capable of moving from tiller to tiller.  Where newly-emerged reseeds are attacked, complete plant loss can occur, necessitating further redrilling.

The likelihood of new leys being attacked can be determined using the Dursban* WG Frit Fly Risk Assessment Chart.  Where high risk is indicated apply Dursban WG at 1.0 kg/ha in 200 to 1,000 lites of water per hectare.  Treatments should be made between drilling of the reseed and emergence of new plants.  Use of the full rate of Dursban WG at this timing will also give residual control of newly emerging Leatherjackets.

In moderate risk situations, the Integrated Pest Management (IPM) rate of 0.45 kg/ha can be used, following the same water volume and timing guidelines as outlined above.  Applications of the IPM rate of Dursban WG allows natural enemies of Frit fly to survive, thereby prolonging the period of control.
