What’s the current situation?

• According to the SCN Coalition, soybean cyst nematode (SCN) resistance to PI88788 is on the rise.
• In Ontario, the organization reports 33% of SCN populations are showing elevated reproduction on PI88788 (>10% reproduction).
• In the US Midwest, the situation is much worse.
• It’s not too late to counter this road to resistance in Ontario.

What can I do to manage SCN resistance?

• Take a soil test to find out if you have SCN.
• Rotate resistant varieties. Rotating varieties with the same source of resistance is also helpful.
• Rotate to non-host crops.
• Consider using a seed treatment to add a second effective mode of action against SCN.

Which seed treatment should I choose?

We have two products available in 2023 that can provide that second mode of action to deliver SCN suppression for your soybeans: Draco™ and Saltro^®. Read on to see which option is best for you:

	Draco	Saltro®
What does it do?	Partial suppression of SCN and Rhizoctonia Improves water use efficiency (WUE)	Suppression of SCN Control of sudden death syndrome (SDS)
What is it?	Dual-strain bacteria biological seed treatment Active ingredients: Bacillus subtilis and Bacillus licheniformis	SDHI seed treatment Active ingredient: ADEPIDYN®
Yield impact	Healthier and stronger root system Improved yield potential: 1.3 bu/ac average improvement in ON in 2021-2022 (n=25)	SDS - Suppresses late season symptoms of SDS (premature defoliation and reduced pod fill) 4.3 bu/ac average improvement under heavy SDS/SCN pressure in ON from 2018-2020 (n=33) SCN – Suppresses entry of nematodes and reduces cyst formation on roots. 3.1 bu/ac average improvement under SCN pressure (n=10)
Treating highlights	2 x 9.46 L cases 1 jug treats approximately 600 units 15.2 mL/seed unit (140,000 seeds) or approximately 76.2 mL/100 kg	2 x 10 L cases 1 jug treats approximately 400 units 100 mL/100 kg seed
