Hi Terry –
Yes, Surround WP will control apple maggot damage. The product forms a barrier film, which acts as a broad spectrum crop protectant for controlling damage from various insects and disease pests. Also, some apple cultivars have shown less bitter pit and corking when used all season long.
To protect trees from apple maggots apply two sprays seven days apart before expected oviposition (identified as small pinpricks made on the apple surface) or first detection of infestation. Continue applications every 7-14 days to keep fruit completely covered during egg laying.
Note: Red Sphere Traps placed throughout the canopy can help you determine where to treat and pest levels.
Hope this helps!
OK Thanks. Does it make sense to start applying after blossom petal drop? Also I was planning on using the fruit nets I bought from Planet natural as a barrier too. ( (The sock like nets). Will the two products work together?
Hi Terry –
Yes, the product label states that Surround WP often enhances fruit quality if applications start at petal fall and are continued until mid to late season. Also, I see no problem using Harvest Guard with Surround WP.
Hope this helps!
