Crop Protection

What is biological crop protection?

Biological crop protection, often referred to as biocontrol, is a natural and sustainable approach to managing pests and diseases in agriculture. Instead of relying on synthetic chemicals, beneficial organisms such as predatory insects, parasitic wasps, predatory mites, nematodes, and microorganisms are used to control pests and diseases. Unlike conventional chemical pesticides, which can have negative impacts on the environment and non-target organisms, biological crop protection is both eco-friendly and sustainable, ensuring the health of crops without compromising the environment.

Advantages of biological crop protection

Easy to use and integrate

Biocontrol agents can be integrated into existing farming practices and complement other sustainable approaches, such as organic farming and integrated pest management (IPM). Biological crop protection often doesn’t require any specific application equipment, e.g., beneficial nematodes can be tank mixed with other crop protection solutions.

No chemical residues

Biologicals leave little to no residues on crops. This enhances food safety and reduces the risk of pesticide residues in the food chain, addressing consumer concerns about chemical exposure. Consequently, adopting biological crop protection practices allows you to meet the increasingly strict requirements set by retail, including supermarkets, ensuring that your produce aligns with their quality and safety standards.

No pre-harvest intervals

Most biological crop protection products do not require a pre-harvest interval (PHI) due to the inherent safety. These agents do not pose risks to human health or the environment.

Minimal resistance against pests and diseases

Biological control agents, such as beneficial insects, mites and nematodes, provide long-lasting pest management solutions. Pests typically do not develop resistance to natural enemies compared to chemical pesticides.

Soil health and biodiversity

Chemical pesticides often harm soil organisms, pollinators, and beneficial insects, while biocontrol solutions enhance soil and plant health. When microorganisms establish themselves in the soil, they create a fertile and balanced environment, promoting crop growth.

Utilizing biological crop protection also preserves natural occurring beneficial insects and organisms, which supports biodiversity. Good soil health and biodiversity contribute to a more resilient plant, maximizing your yield.

Prepared for the future

By adopting biocontrol in advance of chemical bans, growers can develop expertise to fine-tune their pest management practices. Growers will be ready to meet future challenges with confidence and a well-established understanding of biocontrol's benefits.

Lower risk to human health

Biological crop protection poses minimum to no risks to growers and consumers. It reduces exposure to toxic chemicals, promoting safer working conditions and healthier food products.

Beneficial organisms: Key players in crop protection

Predatory mites

Predatory mites are tiny arachnids that play a vital role in biological pest control. These beneficial mites are natural enemies of plant-damaging pests, such as spider mites, whitefly and thrips. Predatory mites feed on these pests, helping to keep their populations in check and protect crops from damage.

Beneficial nematodes

Beneficial nematodes are microscopic roundworms that play a crucial role in biological pest control. They are considered "beneficial" because they parasitize and kill insect larvae, effectively managing pest populations.

Parasitic wasps

Parasitic wasps are small insects that play a crucial role in natural pest control. They are called "parasitic" because they lay their eggs inside or on harmful pest insects, which eventually kills the pest insect.

Predatory insects

Predatory insects actively hunt and consume other insects and mites, often considered pests. Ladybugs, lacewings, predatory bugs, among others are natural enemies of various agricultural pests and play a vital role in biological pest control.

Microorganisms

Beneficial microorganisms, often referred to as biopesticides, can target and control various insect pests and diseases. Beneficial microorganisms can also act as natural antagonists to plant pathogens, suppressing disease-causing organisms and preventing infections.

What are biocontrol agents?

Biocontrol agents refer to products and methods that are based on living organisms or their derivatives, to control pests and diseases. Unlike traditional chemical pesticides, biocontrol agents are eco-friendly and sustainable solutions that aim to minimize harm to the environment, non-target organisms, and human health.

Biocontrol agents encompass a wide range of approaches, including the use of beneficial insects, predatory mites, beneficial nematodes, and microorganisms like bacteria and fungi. Biocontrol agents have gained prominence in modern agriculture as a vital component of integrated pest management (IPM) and sustainable farming practices, offering effective alternatives to conventional chemical interventions.

Biological crop protection vs. chemical pesticides

Choosing biological crop protection over chemical pesticides aligns with the broader goals of sustainable agriculture, promoting environmental health, food safety, and long-term crop resilience while minimizing adverse effects on ecosystems and human well-being.

Biological crop protection relies on nature's own mechanisms to control pests and safeguard crops. It promotes ecological balance, minimizes harm to non-target species, and supports long-term sustainability.

On the other hand, chemical pesticides are synthetic compounds designed to kill or deter pests and pathogens, their use can pose risks to human health and food safety. While they can be effective in the short term, they often come with environmental concerns, including harm to beneficial insects, soil degradation, and pesticide resistance.
