Best Treatment for Pest and Diseases in Farming
Exclusion, eradication, protection, and immunization are the four general disease control concepts (the latter is more correctly called resistance because plants do not have an immune system in the same way that animals do).
Definition of IPM
IPM entails using several ways of control, such as cultural, physical, chemical, and biological measures, in the most compatible way feasible to lower the insect population level below the Economic Threshold Level (ETL).
IPM Approach to Managing Tomato Pests and Diseases
The following components comprise Integrated Pest Management:Cultural practices
• Chemical control
• Biological control
• Mechanical Control
• Physical Control
• Botanical Pesticides
• Bio-intensive IPM
Cultural Control of Diseases and Pest
Certified Seeds:
It is best to use certified seeds that are free of insects and disease-causing organisms. This can help to prevent pest species from spreading through seeds.
Time of Sowing:
The extent of harm is determined by the synchronization of sensitive host crop stages and pest species. Asynchronization can be done by adjusting the sowing timing.
Judicious and Proper Application Fertilizers:
The application of manures and fertilizers at the appropriate time can directly manage insect infestations. Excess nitrogenous fertilizer application promotes bugs. Phosphorus fertilizer has been shown to lower jassid occurrence.
Summer Ploughing:
Ploughing the field after summer showers, clearing crop debris from the field, and exposing different stages of insects, such as eggs, larvae, and pupae, to sunlight all help to minimize pest abundance and prevent pest population increase.
Water Management:
The availability of sufficient water at the appropriate moment is critical to the survival of the plants. Insect pest growth and development can be aided or hampered by water. Cutworms, slugs, and other pests are drawn to wet soil. Water stress has been used to control whitefly (Bemisia Tabaci).
Trap Crop:
Planting yellow tall marigold (Tagetes Spp.) or bidil rustica tobacco (1:5) around tomato has been found to be beneficial. The inundation of Helicoverpa adapted strain of egg parasitoid (Trichogramma Chilonis) might destroy all H.Armigera eggs placed on yellow Tagetes flowerbuds. The main tomato crop is also sprayed with HaNPV or Bt, both of which are Trichogramma-compatible.
Weed Management:
Weeds act as alternate and associate hosts for a variety of insect pests. Weeds help insect pests grow and flourish by supplying nourishment and ovipostion substrates. As a result, removing weeds directly controls insect population growth.
Crop Rotation:
Monoculture aids in the feeding of insect pests throughout the year and contributes to significant harm caused by them. Crop rotation is recommended to avoid monoculture. Monoculture of cotton, tomato, and brinjal is especially discouraged.
Post-Harvest:
Crop residue burning or grazing by cattle or sheep kills the egg masses, larvae, and pupae present in the field, limiting the survival and spread of these dangerous organisms. After picking, carefully destroy any damaged or diseased tomato fruits.
Biological Control of Diseases and Pest
Biological control of insect pest refers to the study and use of natural enemies of insects such as predators, parasites, and viruses by humans to regulate pest populations below economic harm levels.
Biofungicides, biobactericides, and bionematicides are biological agents used to regulate fungi, bacteria, and nematodes, respectively. Different modes of action that target the pathogen, plant, or environment are used in product development.
Predators:
Lady Bird Beetle: This insect feeds on aphids.
Chrysoperla carnea: This insect's larvae eat on all soft-bodied insects such as aphids, jassids, white files, mealy bugs, and so on.
Parasites
Egg parasite: Trichogramma chilonis parasites egg of Helicoverpa armigera.
Larval parasite: Bracon hibitor parasites larvae of H.armigera.
Egg larval parasite: Copidosoma kohleri parasites egg of potato tuber moth and comes out at larval stage by killing the pest.
Pathogens
Bacteria: Bacillus thuringiensis causes disease in a variety of lepidopterous pests.
Virus: Despite several reports of entomopathogenic viruses, Nuclear Polyhedrosis Virus (NPV) and Granulosis Virus (GV) are routinely used in the treatment of insect pests.
Fungus: The plant Beauveria bassiana is used to suppress lepidopterous pests.
Mechanical Control of Diseases and Pest
Hand picking of larvae:
Because cutworm and leaf-eating caterpillar larvae are slow, they can be easily caught and exterminated by hand.
Trenching the Field:
Pests such as army worms and grasshoppers march from one field to the next, which can be avoided by trenching in the field.
Physical Control of Diseases and Pest
Burning;
To avoid pest spread, damaged fruits and crop debris should be burned.
Refrigeration;
Fruit and vegetable storage in the refrigerator lowers pest infestation.
Moisture:
At optimum moisture, there is no infection, whereas high moisture in the field enhances insect infection.
Use of Light:
Many pests, such as the hairy caterpillar and the stem borer, are caught using light traps.
Chemical Control of Diseases and Pest
The most prevalent way of pest control is chemical methods. As a result, their prudent application is urged, which includes avoiding prophylactic sprays, employing strip treatment, applying to only those regions with high pest occurrence, applying to the soil to avoid direct contact with natural enemies, and using selective or non-persistent pesticides.
Pesticides are applied to the skip row of vegetables. Safer pesticides for use in conjunction with natural enemies have been identified-among chlorinated hydrocarbons, Endosulfan, among organophosphates-Phosalone, Monocrotophos, Oxydemeton Methyl, and Dichlorvos, and among carbamates-Carbaryl-have been found to be relatively safer to many commonly used natural enemies.
Botanical Pesticides of Diseases and Pest
For pest management, farmers used a range of plant products and extracts. Neem (Azadirachta indica), pongamia (Pongamia glabra), and manhua (Madhuca indica) are the most often used botanicals. Neem seed kernel extract (2 to 5%) has been shown to be effective against a variety of pests, including cutworm, plant hoppers, leafhoppers, tobacco caterpillars, aphids, and mites.
Mahua seed kernel extract (5%) kills sawflies (Athalia lugnes proxima) and other insects. Targets or asparagus root extracts are effective nematicides for plant parasitic nematodes. Similarly, leaf extracts from several higher plants have been shown to inhibit a variety of fungal infections.
Neem seed extract was utilized to treat root-knot nematode in tomatoes.
Bio-intensive IPM
Biologically intensive IPM (BIPM) is a variation on the core concept of IPM that focuses on host-plant resistance, biological control, and cultural control, as well as the use of biorational pesticides that can be integrated with these.
Tomato fruit borer is controlled biologically by releasing T. brasilience, T. pretisoum, or T.chilonis (strain BioH1) six times at 50,000 per hectare, with the first release occurring 30 days after transplantation.
Final Thought.
Buying disease-resistant seeds and seedlings can help them get off to a good start, and make sure to provide enough space between plants to allow for optimal airflow.
Before planting, amend the soil as needed, water at the soil line rather than sprinkling the leaves, and keep a watch out for pests and typical disease symptoms.
