An Overview Of Major Pests & Diseases In Agriculture

“The earth laughs in flowers, but pests and diseases can bring tears to a farmer’s eyes.” 

As we sow the seeds of agriculture, we face the constant threat of pests and diseases that lurk in the shadows, ready to wreak havoc on our crops. From the buzzing buzz of insects to the stealthy invasion of pathogens, these tiny adversaries can have a colossal impact on the productivity and quality of agriculture in India. 

But fear not, for with the right knowledge and tools, we can rise above these challenges and safeguard our agribusinesses. In this blog, let us delve into the world of pests and diseases in agriculture, explore the impact they have, understand the importance of pest management, and discover why Kheti Buddy is the ideal companion for effective pest management.

Emerging Pests And Diseases In Agriculture

  • Fall Armyworm (Spodoptera frugiperda): Fall Armyworm, an invasive pest native to the Americas, has rapidly spread to many countries, including India. It attacks a wide range of crops, including maize, rice, sorghum, and vegetables, and can cause significant yield losses if not effectively managed.
  • Pink Bollworm (Pectinophora gossypiella): Pink Bollworm is a major pest of cotton in India. Over the years, it has developed resistance to genetically modified Bt cotton, which was initially introduced to control it. This has resulted in increased pesticide use and reduced cotton yields, posing challenges to cotton farmers in India.
  • Tomato Leaf Curl Virus (ToLCV): Tomato Leaf Curl Virus is a viral disease transmitted by the whitefly (Bemisia tabaci) that affects tomatoes and other solanaceous crops in India. It causes leaf curling, stunting, and reduced yields, leading to significant economic losses.
  • Fusarium wilt (Fusarium oxysporum): Fusarium wilt is a soil-borne disease that affects several crops, including tomatoes, bananas, and chickpeas, in India. It causes wilting, yellowing, and vascular discolouration, leading to reduced plant growth and yields.
  • Maize Lethal Necrosis Disease (MLND): Maize Lethal Necrosis Disease is a viral disease that affects maize crops in India, causing severe stunting, necrosis, and reduced yields. It is transmitted by insect vectors and has emerged as a crucial threat to maize production in some regions of India.
  • Red Rot (Colletotrichum falcatum): Red Rot is a fungal disease that affects sugarcane crops in India. It causes the rotting of sugarcane stalks, leading to reduced sugar recovery and economic losses for sugarcane farmers.
  • Bacterial Leaf Blight (Xanthomonas oryzae pv. oryzae): Bacterial Leaf Blight is a bacterial disease that affects rice crops in India. It causes leaf wilting, yellowing, and blighting, leading to reduced grain quality and yields.

How Can They Impact Seamless Agricultural Operations? 

  • Reduced Crop Yields: Emerging pests and diseases can cause significant yield losses in crops. For example, Fall Armyworm, Pink Bollworm, and Tomato Leaf Curl Virus can lead to stunted growth, leaf curling, and other symptoms that reduce plant vigour and productivity. This can result in lower crop yields, leading to reduced income for farmers and food shortages.
  • Lower Crop Quality: Pests and diseases can also impact the quality of agricultural produce. For instance, diseases like Fusarium wilt and Red Rot can cause rotting, discolouration, and other defects in crops, reducing their market value and quality. Bacterial Leaf Blight in rice can also affect grain quality, leading to reduced milling recovery and poor grain appearance.
  • Increased Pesticide Use: To manage emerging pests and diseases, farmers may resort to increased use of chemical pesticides, which are responsible for resulting in highly negative impacts on the environment and overall human health. Overreliance on pesticides can lead to the development of pesticide resistance in pests, damage to non-target organisms, contamination of soil and water, and pose health risks to farmers and consumers.
  • Economic Losses: Crop losses due to pests and diseases can result in significant economic losses for farmers. Lower yields, reduced crop quality, increased pesticide use, and additional costs associated with pest and disease management measures can all contribute to financial hardships for farmers, affecting their livelihoods and economic well-being.
  • Disruption of Trade: Pests and diseases can also disrupt the trade of agricultural commodities. Quarantine measures, export restrictions, and other trade barriers may be imposed in response to the presence of emerging pests and diseases, resulting in reduced market access and export opportunities for farmers and agribusinesses.
  • Increased Production Costs: Managing emerging pests and diseases may require additional investments in pest management practices, such as purchasing resistant varieties, adopting integrated pest management strategies, and implementing biosecurity measures. These additional production costs can strain farmers’ budgets and reduce their profitability.

Pest Management & Its Techniques 

  • Cultural Practices: Cultural practices involve modifying agricultural practices and cropping systems to manage pests. Examples include crop rotation, intercropping, the use of trap crops or repellent crops, and planting pest-resistant crop varieties. These practices can help disrupt the pest life cycle, reduce pest populations, and promote natural enemies of pests.
  • Biological Control: Biological control includes the use of natural enemies, including predators, parasitoids, and pathogens, to control pests. This can include the release of beneficial insects, like ladybugs or lacewings, or the use of microbial agents, such as Bacillus thuringiensis (Bt) or entomopathogenic nematodes, that target specific pests. Biological control can be an effective and environmentally-friendly approach to managing pests.
  • Chemical Control: Chemical control includes the usage of pesticides to manage pests. This can include insecticides, fungicides, herbicides, and other chemicals. Chemical control should be used judiciously, following recommended application rates, and with consideration for potential impacts on non-target organisms, resistance management, and environmental concerns.
  • Mechanical and Physical Control: Mechanical and physical control methods involve the use of physical means to manage pests. Examples include hand-picking or trapping pests, using barriers like nets or screens, and using physical devices like pheromone traps or ultraviolet light traps. These methods can be labour-intensive but can be effective in managing pests in localized areas.
  • Genetic Control: Genetic control techniques involve the use of genetically modified organisms (GMOs) or genetically resistant crop varieties to manage pests. For example, Bt cotton, which is genetically engineered to express a toxin derived from Bacillus thuringiensis, can control cotton bollworm, a major pest in cotton production. Genetic control methods require careful regulation and monitoring to prevent potential environmental and social impacts.
  • Monitoring and Scouting: Regular monitoring and scouting of pests and their populations are crucial components of pest management. This involves regularly inspecting crops to identify and monitor pest populations, assessing pest damage levels, and making informed decisions on appropriate pest management strategies.
  • Integrated Approaches: Integrated pest management involves combining multiple pest management techniques in a coordinated manner to achieve optimal results. This can include using a combination of cultural practices, biological control, chemical control, and other strategies tailored to the specific pest and crop situation. Integrated pest management seeks to minimize the use of chemical pesticides while maximizing the use of sustainable and environmentally-friendly approaches.

Pest management is of utmost importance in agribusiness as it directly impacts the productivity and quality of agricultural produce. Uncontrolled pest populations can result in significant crop losses, reduced yields, decreased crop quality, and increased production costs. Inadequate pest management can also lead to the development of pesticide resistance, environmental pollution, and harm to beneficial organisms, thereby posing risks to the sustainability of agriculture.
