Agricultural pest alert: main threats and how to combat them

Agricultural pests represent one of the biggest challenges for the agricultural sector.

Whether for small farmers or large producers, these organisms can compromise productivity, food quality and, ultimately, global food security.

Therefore, identifying the main threats and knowing effective control strategies is essential to ensure sustainable and profitable agriculture.

In this article, we'll explore the most common pests, the damage they cause, and the best tactics for controlling them.

In addition, we will present data organized in tables to help understand the impacts and forms of management.

Main Threats in the Agricultural Pests Scenario

Agricultural pests include a wide range of organisms, such as insects, mites, fungi, bacteria, nematodes and even some weed species.

In this sense, each of them has specific characteristics that determine their ability to cause damage.

1. Insects as Visible Enemies

Among the main insects that threaten plantations, caterpillars, grasshoppers and fruit flies stand out.

Caterpillars such as the fall armyworm (Spodoptera frugiperda) attack crops such as corn and soybeans, causing major losses.

In this way, they destroy leaves and compromise photosynthesis, reducing plant growth.

Locusts are known for their devastating outbreaks across large areas of cropland.

The desert locust (“Schistocerca gregaria”), for example, can consume a huge amount of vegetation in a short period of time, placing entire regions in a state of emergency.

Another notable insect is the fruit fly (Ceratitis capitata), which attacks fruits such as mango, orange and peach.

In short, it lays its eggs inside the fruit, compromising its quality and making it unfit for consumption.

2. Don't Underestimate Fungi

Fungi also top the list of threats to crops.

Species such as Asian rust (Phakopsora pachyrhizi) attack soybean plants, while white mold (Sclerotinia sclerotiorum) can affect crops such as beans, potatoes and sunflowers.

In this sense, these organisms generally thrive in conditions of high humidity and mild temperatures, which highlights the importance of climate monitoring.

These fungal pests not only compromise productivity, but also generate additional costs with fungicides, making management even more challenging.

Inadequate control can lead to devastating epidemics, with significant crop losses.

Agricultural Pests: Impacts of Pests on the Agricultural Sector

The presence of pests agricultural directly affects the productivity and profitability of the producer.

The damage caused varies according to the type of pest, the crop affected and the intensity of the infestation.

How to Combat Agricultural Pests

To tackle the problem, integrated pest management (IPM) emerges as the most efficient solution.

This approach combines cultural, biological, chemical and mechanical methods to minimize pest impacts while prioritizing sustainability.

1. Biological Control: A Sustainable Alternative

Biological control uses living organisms, such as natural predators, to reduce pest populations.

For example, Trichogramma wasps are released to combat caterpillars, while ladybugs help control aphids.

This strategy reduces dependence on pesticides, reducing environmental impacts and costs for the producer.

Furthermore, another positive aspect is that biological control promotes ecological balance.

However, detailed planning is essential to ensure that the use of these organisms is effective and safe.

2. Cultural Management: Prevention is Everything

Cultural management includes practices such as crop rotation, planting resistant varieties, and controlling soil moisture.

Rotation, for example, breaks the life cycle of pests, reducing their proliferation.

Furthermore, resistant varieties are developed to tolerate specific attacks, ensuring greater productivity.

Another essential measure is the use of controlled irrigation techniques, which can avoid excess water, minimizing the occurrence of fungi.

Although these strategies require planning, the long-term results are rewarding.

3. Chemical Control: Responsible Use

Chemical pesticides continue to be an important tool, but they must be used responsibly.

The correct choice of product, the appropriate dosage and the right time of application are crucial to avoid pest resistance and environmental contamination.

Constant monitoring of crops helps determine the ideal time for application, reducing waste.

Furthermore, the use of biological pesticides is a safer alternative, reducing risks to the soil and pollinators.

Agricultural Pests: Trends and New Technologies

The adoption of advanced technologies is transforming the fight against agricultural pests.

Drones, sensors and artificial intelligence (AI) systems allow more precise monitoring of crops, identifying critical infestation points and enabling localized application of pesticides.

This precision reduces costs and environmental impacts, benefiting the farmer and the ecosystem.

Additionally, startups and biotechnology companies are developing innovative products, such as highly efficient biopesticides, that offer alternatives to traditional chemical pesticides.

These solutions help meet growing demands for more sustainable agriculture.

Another example is the use of genetically modified seeds, which have built-in resistance to certain pests, reducing the need for external interventions.

Bringing together emerging technologies and traditional practices could be the key to more effective pest management in the future.

Education and Training in Pest Control

Finally, education and training of farmers plays an essential role in tackling agricultural pests.

Without adequate knowledge, producers may implement control methods inefficiently or even harmfully.

It is vital that there is access to training on integrated management practices, correct use of pesticides and new technologies.

Government institutions, NGOs and the private sector have a fundamental role in this process.

Partnerships between these agents can make rural extension programs, workshops and distribution of informational materials viable.

Furthermore, the use of digital platforms, such as apps and online courses, can facilitate access to knowledge, especially in remote areas.

Education also contributes to a cultural change, encouraging more sustainable agricultural practices.
