FAQ about the value of Seed Applied Insecticides
1. Do Seed Applied Insecticides enhance crop quality and yield?
Yes. SAIs protect the seed and seedlings from pests, ensuring that the plants get off to a healthy, vigorous start, which ultimately translates into quality and yield improvements. This protection is key to agricultural production in Canada as damaging insect pests have been documented in all growing regions of the country for each major agricultural crop.
2. What role do Seed Applied Insecticides play in an Integrated Pest Management (IPM) program?
SAIs, when used as part of a preventative IPM program, can minimize the need for replanting crops due to damage from a variety of pests (for example, aphids, wireworms and flea beetles), as well as contribute to a decrease in overall pesticide use by reducing the need for foliar insecticides.
SAI protection is particularly important in instances where there is no curative option for salvaging plant health after insect damage has occurred.
3. Are there other environmental advantages to Seed Applied Insecticides?
Yes. SAIs offer several environmental benefits including:
4. What other benefits do Seed Applied Insecticides provide?
- A significantly lower amount of active ingredient per acre compared to foliar and soil-applied pesticides
- Direct application to the seed, which minimizes off-target drift
- Reduced impact on non-target organisms, including beneficial insects
- Protection from increased pest pressure associated with a range of agronomic practices including reduced/no-till field conditions
The value of SAIs extends beyond pest control and includes numerous agronomic and production benefits. SAIs also:
5. Are there benefits to using Seed Applied Insecticides when there is low-to-moderate insect pressure?
- Optimize seeding rates due to improved plant stand
- Minimize the need for replants
- Extend the application window for in-season, foliar pesticide applications (when needed)
- Support earlier planting practices, which help to maximize labour and production efficiency
- Complement trait technology to manage insect pests (where there are no traits available to control insect pests and/or to provide a different mode of action for resistance management)
Yes. Insect pests can cause damage to crop growth, quality and yield even at low-to-moderate pressures. Small populations of certain pests may have a detrimental effect, with the result that the seedling may never emerge or the health of the plant may be compromised. If untreated seed is put into the ground where pests exist, there is no way to protect the seed retroactively. In either of these scenarios, the crop may have to be replanted at significant cost.
Additionally, even in the absence of pest pressure, SAIs provide strong plant establishment, health and vigour by protecting and strengthening the plant at crucial times of development (i.e. germination and root growth). This allows plants to better compete with weeds and diseases and deal with abiotic stresses such as cool soil temperatures or dry conditions at planting.
