How to Manage Pests

Interactive Tools and Models: Dormant Spray Alternatives Calculator

| About the calculator | Calculator inputs | Spray alternatives |

This calculator* estimates the costs of using organophosphate (OP) dormant sprays and selected alternative practices. When compared to conventional OP dormant sprays, the alternatives listed in the calculator offer favorable levels of pest control efficacy with comparable ranges of cost, while affording a reduced risk of aquatic toxicity.

Select a crop:

A good monitoring program may indicate that no treatment is needed. If a treatment is warranted, select an alternative to determine cost:

 1:  Conventional dormant OP + oil spray   [Explain]
 2:  No dormant OP spray   [Explain]
 3:  Alternate-year dormant OP + oil application   [Explain]
 4:  Bloomtime Bt sprays   [Explain]
 5:  Spinosad + oil as a dormant spray   [Explain]
 6:  Conventional non-OP insecticide as a dormant spray   [Explain]
 7:  Pheromone mating disruption for peach twig borer, bloomtime Bt sprays   [Explain]
 8:  Pheromone mating disruption for peach twig borer, non-OP + oil as dormant spray  [Explain]
