Which two factors determine the economic threshold for greenbug in sorghum?

The economic threshold for pests like the greenbug in sorghum is significantly influenced by plant size and maturity. Plant size refers to the overall growth and lushness of the sorghum, which can impact its ability to withstand pest damage. Larger, more developed plants may be more resilient and can often tolerate a certain level of pest presence without suffering significant losses.

Maturity is equally crucial, as younger plants are generally more vulnerable to pest infestations compared to mature plants. Depending on the growth stage of the sorghum, the impact of the greenbug can vary, necessitating a careful assessment of when to take action to manage the pest. This emphasizes the importance of knowing both the size and maturity of the plants to establish a precise economic threshold for intervention.
