QUIZ – Moisture

Three quick questions on moisture – two related to germination of annual weeds and one on water reserves in the soil.

1. What are these seedlings?

Hemp nettle

Kochia

Stinkweed

2. What did the CCC agronomy specialist recommend the farmer do about the weed seedlings in question 1?

Wait until they’re big enough for an accurate ID

Wait until leaf area increases enough to take in a sufficient amount of herbicide

Spray now with a tank mix that will capture a broad spectrum of weeds

Check that other weeds have also emerged before spraying
