fruit tree sprays

How many times per year I can use A Complete Fruit Tree Spray on my grape tree? I have a wine tree and sprayed already twice, May 16 and 30 this year. Two weeks later I noticed that were bugs, new leaves started too curl, some grapes became dark, leaves were eaten by a small beetle.
Should I spray again?

This is the spray I have: Bonide, A Complete Fruit Tree Spray

On directions it said – “no more than two applications per year!” I already did two, but bugs appeared after 2 weeks. Could you tell me what to do, please?

Always follow the manufacturer directions and application procedures.
I would recommend using Neem Oil to treat the grapevine.
