NOTES:  

  • No endorsements intended. 

  • If you compare the rate of an insecticide by itself (like carbaryl), then by how much is in orchard spray premixes, you will find the orchard spray is SIGNIFICANTLY less and may not provide sufficient insect control.  Better off tank mixing individual components in many cases. 

  • Know the pH of your water source and how it may change efficacy. 

On Fungicides 

  • To reduce likelihood of resistance, never use one active ingredient for more than two applications in a row.  

On Insecticides 

  • For codling moth, alternate active ingredients
