What is the difference between a contact and systemic herbicide? -
ANSWER--Contact herbicides kill only the green part of the plant where

herbicides move throughout the plant (foliage or root absorbed).

What information should be recorded when you monitor your control
, strategies? - ANSWER--- Which control method(s) you're using
- Start and end dates

ANSWER-- For safety, aesthetics, lower maintenance, etc.
What type of control method is shading and where is it used? - ANSWER-
- Cultural control - shading aquatic plants with floating structures or dye
placed in the water
Define cultural control - ANSWER--Create optimal growing conditions for
desired plants and unfavorable conditions for pests
Define biological control - ANSWER--Enhancing the effects of natural
enemies on pests
What are the four stages of plant development? - ANSWER--1. Seedling
