Пожалуйста, помогите перевести следующую фразу: trait/herbicide combination

Can you tell me a little bit about your operation?
Sure, it’s been in the family for three generations.
We mostly grow corn and wheat.
Dan:
How big is the operation?
It’s about 1,000 acres (405 hectares).
It sounds like that size keeps you pretty busy.
What corn products did you use on the operation last year?
We used a *trait/herbicide combination* to help control both weeds and pest.
Where you happy with that choice?
Yes, we made our operational goals so we were happy with both the yield and the control.

A bit later in the conversation, in reference to Tim’s comment on the operation’s use of a trait/herbicide combination to help control weeds and pest, Dan asked, “Where you happy with that choice?”
What’s is the trait/herbicide program that you used?

комбинация гербицидов направленного действия?
комбинация гербицидов с различным спектром действия? (как здесь http://www.zerno-ua.com/?p=10446)

Непонятно как-то...
Если против сорняков - гербициды, а против вредителей - пестициды, то, получается, trait - это селективный пестицид?...
Но почему это говорится в ответ на вопрос про corn products? Может быть, corn (protection) products?
