Which practice is considered an appropriate measure for disease control?

Utilizing planting dates and populations that minimize disease is an effective measure for disease control because it takes into account the life cycle of plants and pathogens, as well as environmental conditions that can either promote or hinder disease development. By strategically timing planting and selecting appropriate plant populations, you can reduce the likelihood of disease onset. For example, planting at times when certain pathogens are less active or using resistant crop varieties can significantly lower disease risk. This proactive approach helps create an environment that is less conducive to the emergence and spread of diseases, ultimately leading to healthier crops and improved yields.

The other options do not reflect viable disease control practices. High doses of pesticides may lead to resistance in pathogens and harm beneficial organisms, while delaying planting until after disease appears does not prevent the issue and may exacerbate crop losses. Ignoring environmental conditions overlooks critical factors like humidity and temperature that influence disease dynamics, limiting the effectiveness of any disease control strategy.
