POTATO.THRIPS.FERNANDEZ.1999

 
METHOD: Visual Examination CONDITIONS: Green House and Field METHOD NARR: The plants were evaluated in the field for three consecutive seasons. The most susceptible entries were dropped after each planting. Water was applied ton and not sprinkled so as not to wash away the thrips. Field resistance was evaluated at 1 month, 2 months and 2.5 months of age. Entries that showed resistance in the field were re-evaluated in the GH using the same ratinumerical (1-5) system was used to correspond to a highly resistant through highly susceptible rating scheme based on degree of damage to the plant. AUTHOR EXPLANATION: It is noted that the first two field trials generated unroncentration of thrips. When insecticides are applied to inhibit unwanted insects, the thrips populations increase.
