PRE-EMERGENT SOIL THROW EFFECTS

seeding interaction with pre-emergent herbicides

Key Points

  • Visual crop bleaching from Overwatch at 2 weeks after seeding. Crop has since recovered.

  • No knockdown was added, to highlight Pre em effects

  • Hard to get seeder placement right. Chose rows most appropriate in counts

  • Some small levels of bleaching evident in Voraxor treatments.

  • Slight reduction observed in plant numbers in on row and luximax plots. Clods/blocking up caused lower plant establishment

​

Aim

To determine whether placement (inter/edge/on row sowing) has any effect on the level of IBS herbicide damage observed.

​

Background

With continued focus on optimising seed placement with marginal moisture during seeding the focus on soil throw effect can often be missed. Whether or not pre-emergent chemicals have an increased effect on crops when seeded inter/edge/on row could add a layer of complexity to choosing pre-emergent chemistry as well as seeder set up. Investigating where these differences may lie is important to ensure that we appropriately choose the correct pre-em package especially where newer chemistry is becoming available in the market.
