Integrated Pest Management (IPM) All Answers Correct 1.Proper pest identification and field scouting is the first two most important steps -correct pest identity -pest biology and life cycles -most susceptible stage in the life of the pest -how the pest grows under specific conditions -how the pest survives and lives -how the pest spreads -what are the effects of environmental factos on the pest -Insects and disease, what are the damage symptoms -what are the natural enemies 2. Field scouting is a systematic sampling of the pest populations and recording the pest -weeds - number per given area (density) and pattern in the field -Insects - stage or size, symptoms and level of damage on the crop and symptoms and level of damage -Disease-severity, symptoms and level of damage Abiotic noninfectious diseases. cannot multiply within the host and cannot be transmitted from plant to plant. result of unfavorable environmental or chemical conditions such as unfavorbable temps, soil compaction, drought, flooding, nutrient imbalances, air pollution or chemical excesses and misapplication Amaranthaceae - Pigweeds Prolific seed producers.
