Waiting for weeds to emerge, identifying the weed species and population present, assessing whether control is needed, and, if needed, choosing the most appropriate control. The most appropriate control can be determined from available options once the pest has become apparent. Thresholds, when available, can be used to determine the need to apply control measures. Potential for high levels of an insect pest are known to exist. Protecting the host plant prior to infection is desired when conditions are conducive for infection.
Seed treatments are appropriate.
Potential weed pressures are uncertain, and decisions can be made after weeds emerge. High annual weed populations are known to exist, and decisions can be made after weeds emerge. Insect pest and economic injury levels can be assessed prior to making application decisions.
