enviormental-water deficit/excess, light issues, pollination, planting depth, sunburn/sunscald

Biotic Casual Agents

Fingal, Bacterial, Viral, Insects, Mites, Nematodes, Animals

Diagnostic Steps

Identify Plant, Identify symptoms, inspect entire plant, inspect and evaluate the site, look for patterns, plant maintenance and site history, condense field data, samples and testing

Step 1 in Diagnostic identify plant 

genus,species, cultivar, normal appearance, are cultural needs being met 

Step 2 Identify Symptoms

examine affected portions, describe symptoms, location, size, shape, and color

Step 3 Observe Plant

Step 4 Inspect and Evaluate Site

examine growing enviorment, texture, pH, drainage, soil coverings, irrigation type, surrounding plants, growth obstructions

Step 5 Look for patterns

damage on one side vs both, low vs high areas, abiotic vs, bitotic

Step 6 Review Plant Maintenance and Site History

questions,planting age,methid size, fertilizer use and chemical, past maintenance (pruning), irrigation, water source

Step 7 Condense Field Data

put all steps together and determine possible problems, where injuries is etc

Step 8 Samples and Testing

research, soil ph, texture, OM%, insects ID, water salinity nutrient deficiency, Plant Tissue diseases, deficiency/excess,
