1	IPM Principles William J. Marose Marose Ag-Consulting
2	What is Integrated Pest Management? IPM -is a “common sense” approach that takes the guess work out of managing and controlling pests. -is socially acceptable, environmentally responsible & economically practical.
3	Pests Insects Diseases Weeds Invertebrates Slugs, snails, nematodes Vertebrates Voles, deer, birds
4	Components of IPM Preparation Pest prevention Pest Monitoring Economic Thresholds Management Options
5	Preparation What are the strengths & limitations of your operation (labor, equipment, $, markets) Focus of values: organic, sustainable, conv. Know potential pests & problems. What practices are available to prevent or avoid or suppress these pests.
6	Practices Site selection Resistant varieties Rootstock selection Timing of cutting or harvest Planting date Till for weeds, slugs Use of cover crops for suppression
7	Management & Control Options Biological Cultural Mechanical Chemical
8	Pest Monitoring Visual inspection Pheromone & mechanical traps Degree Day Modeling Disease Forecasting Maryblyt Tomcast Melcast
9	Economic Threshold ET – the point at which cost of damage exceeds cost of control. Based on value of crop vs. cost of treatment Tolerance of pest damage Aesthetics of crop
10	Economic Threshold Over treat Costly in terms of excess control Under treat Costly in terms of reduced crop quality
11	Non-Chemical Pest Control Allows timing specific control Parasite/predator release Mechanical weed control Trap crops Pruning: fireblight
12	Chemical Pest Control Narrow range of target species Used at the lowest effective rate Short lived in the environment Least toxic to beneficial and humans Alternated with other chemical to help prevent resistance REI, Days to harvest
13	Evaluation Short term Was management decision correct? Was control effective? Is additional or different control needed?
14	Evaluation Long term – Will occurrence of pest change production practices? Has it become an established pest? Change in disease or weed pressure?
15	IPM Prescription pest control Socially & environmentally sound Allows the grower to work within values & management plan Based on economic thresholds Has both short & long term benefits
