Green tip is just around the corner! Now is the time to set your plan into action. As the weather warms up, check in with your local agronomist for timely updates on infection periods. 

Scab is high risk and powdery mildew is low risk for developing resistance  

When building a program, keep in mind, apple scab is considered high risk for developing resistance, whereas powdery mildew risk is low. 

Syngenta has three fungicides for apples, and all three come with a different risk level. Check out this table to help plan your program: 

Product	Sequential sprays (#)	FRAC Group	Fungicide resistance risk
	2	3 + 9	Medium
	2	3 + 7	Medium to high
	3	29	Low

​​​​​​​Many scab fungicides contain Group 3, 7 and/or 9. The general rule of thumb is to apply these groups no more than twice sequentially when targeting a high-risk disease like scab.  

What about low resistance risk fungicides?  

A key strategy for resistance management is the inclusion of low-risk fungicides in your spray program. Allegro^® is classified as a low-risk fungicide by FRAC. It’s also the only Group 29 registered in apples.

Can Allegro® be tank-mixed with mineral oil? 

Crop varieties can differ in their response to tank mixes with mineral oil, and environmental conditions can have an influence. 

Without prior experience in your orchard, especially during periods of high humidity and high temperatures, it’s recommended to not tank mix Allegro^® with mineral oils. 
 
These are general considerations. Always consider the specific situation on your field and exercise good agronomic practices.
