Seed treatment is the process of applying additives to seed such as insecticides, fungicides, nematicides, nutrients and biological agents to provide plant protection and growth enhancement benefits during the seedling establishment period.
The first four to six weeks after sowing is a critical period in the life of a new plant, as seedlings emerge and develop their physical make up. Sowing treated seed provides protection during the germination and establishment stages when emerging seedlings are most vulnerable to attack from invasive insect pests and disease pathogens.
Seed treatment can improve seed germination, seedling emergence, plant vigour, stand establishment and total yield, helping to ensure the crop or pasture is on its way to reaching its full genetic potential.
Reduces risk and helps safeguard investment in forage seed. The cost of failed pasture establishment can be in excess of $2,000/ha with lost production and re-planting costs. In a forage crop situation, the loss of plants can significantly reduce potential crop yield, as well as increasing the overall feed cost.
Seedlings protected by seed treatment are in a better position to withstand environmental stresses, including pest and disease pressure. Seed treatment helps maximise seedling establishment and nurture early plant growth, helping ensure the crop or pasture is in a position to reach its full yield potential.
Seed-applied chemicals are target specific against a range of economically damaging insect pests and diseases during the plant establishment period.
Integrated pest management
Complements traditional broadacre crop protection methods and other new plant protection technology such as endophytes, as part of an integrated pest management approach.
Reduced environmental impact
Delivers very small quantities of chemical active ingredient to the soil in comparison to broadacre applications. Chemicals are rigorously tested to ensure they have no detrimental effects on the environment.
Improves sowing accuracy
The addition of seed coating material to seed can increase weight and size to provide a more accurate and uniform spread of seed in aerial oversowing applications and enable uniform plant spacing in precision drilling.
Reduces the need to handle chemicals on farm. It also allows more flexibility when weather conditions make it difficult to apply broadacre crop protection products.
