Although organic methods of pest control are becoming more popular, there are still times when chemical control methods are the best option. In residential and agricultural situations, insecticides can manage pest population that might otherwise boom and destroy valuable plants. That said, it's important to know when to use chemicals and when to try another option first. Environmental responsibility should be a top priority when managing insect populations. Keep reading for more information on when to use chemical pesticides and when to try an organic method first.
Natural pest control
For some households and small farms, natural pest control can work well enough. In some cases, this might mean employing the use of predator insects to control pests that consume crops. According to Clemson University, spiders are among the best predators when it comes to preventing harmful pests. Spiders are omnivores that generally feed on other insects. Other types of predatory insects include lady beetles, praying mantid and lacewings. Many organic farms will purchase predatory insect eggs and hatch them in their crops where they will feed on herbivorous insects.
Other means of nonchemical pest control include wire mesh netting and scents that will keep out larger pests such as deer and rodents. These methods are only useful if they can cover the entire crop. According to the U.S. Department of Agriculture, some synthetic substances such as pheromones, are allowed to be used on crops because they are non-toxic.
Preventing monetary losses
Pesticides become necessary when they will prevent crop losses that would lead to substantial monetary losses. In large-scale operations, pests could cause losses to the tune of hundreds of thousands of dollars. In fact, the University of Pennsylvania estimated that non-use of herbicides would lead to an industry loss of $21 billion.
Farmers mitigate chemical use by using products designed to target specific pests. There's never a one-size-fits-all solution. Using a targeted approach can mean that, overall, a lower amount pesticides are necessary to protect crops.
Speaking with The Food Journal, farmer Katie Sawyer said, "[Farmers] survey the field and crop damage and are exact, within less than an inch, with their application. By only applying the minimum amount, this reduces the potential for run off and adverse affects to the soil."
Chemical pest control is necessary for the level of food production required to sustain the country's growing population. When used properly, pesticides can achieve their desired effect with minimal impact on the environment.
