Seed Treatment Category 4 Exam
Questions and Answers
Typical PPE while treating and handling seed include: - -long-sleeved shirt, long pants,
shoes with socks, and chemical-resistant gloves.
-What must you keep record of? - -Company name and license number
Customer name
Specific site of restricted use pesticide application
date of treatment
Trade name
Application rate and quantity used
Temperature and direction of wind
time application begins and ends
-systemic seed treatment - -penetrates the roots and germinating seed, then moves up
into the stems and leaves
-nonsystemic seed treatment (contact) - -treatment protects ONLY the outside of the seed
or seedling.
-how to check compatibility of products? - -pre-mix a small amount
-What can cause damping off? - -Fusarium, PYTHIUM, Rhizoctonia
-What diseases cause the seed to look fuzzy? - -Aspergillus, Fusarium, Penicilium, or
PYTHIUM
-Seedborne pathogens are? - -carried on the seed coat or within the seed
-Soilborne pathogens survive how? - -in the soil or crop residue and attack seeds or
seedlings after planting
-Back-siphoning - -is the reversal of normal flow in a system caused by a negative
pressure
eg. water pressure is lost and chemicals are sucked out of a mix tank through a submerged
hose into a well or municipal water supply
-Backflow - -Is the reversal of normal flow in a system because the downstream pressure
is greater than the supply pressure
eg. you are using a pumping system to send water up into a tank and a large irrigation
system down the road starts causing the municipal water pressure to drop, the treatment
chemical in your tank will travel back down into the pipe and into the water supply
