BIO PEST CONTROL METARHIZIUM ANISOPLIAE USES IN AGRICULTURE

Bio Insecticides An entomopathogenic fungus called Metarhizium Anisopliae infects insects that come into touch with it. The insect dies as a result of the fungal spores penetrating its exoskeleton and rapidly growing inside it after attaching to its surface, germinating, and starting to develop. The fungus spreads from infected insects to other insects that come in contact with them. Action Method Anisopliae Metarhizium Products are fungi that are harmful to pests. The metarhizium anisopliae conidia adhere well to the skin internodes of the host insect. The conidia begin to grow bud tubes and develop hyphae when exposed to an environment with the right temperature and humidity. Enzymes that mycelia release can dissolve the chitin in insect body walls. Additionally, hyphae infiltrate the host’s epidermis under the pressure of bacterial host invasion before moving gradually inward and infiltrating the adipose tissue and muscle of insects. Insects die as a result of the mycelium growing inside their bodies. Yellow-brown dots can be visible on the body wall when metarhizium anisopliae initially detects host insects. Insects start to exhibit neurological problems as a result of the metarhizium toxin’s effect. Larvae stop eating, show less reaction to stimuli, and eventually pass away. After passing away, the carcass stiffened and the hyphae inside the worm started to spread outward. White hyphae rapidly formed a coating on top of the body. Conidial stalks and conidia subsequently developed on the hypha a day or two later. It either turns dark green or green. Application Processes Foliar Spray (For Bugs & Hoppers): Using hand, ground, or aerial spraying equipment, the substance should be applied to the developing plants. Application to the soil (for vine weevils & root grubs): By mechanical means or by watering plants, metarhizium anisopliae can be sprinkled about the root zone and mixed into the soil. After being filtered through the proper filters, it can also be absorbed into the soil using drip irrigation systems. The frequency of use For four weeks, applications must be submitted at least once per week. Applications every 1015 days are advised for pest issues in greenhouses. The monitoring of pest populations should serve as the foundation for all applications. Dosage Spraying the leaves: 2.5 kg per hectare in 500 liters of water, or 5 mg per liter. The crop canopy affects the spray volume. Application rate per hectare: 2.5 kg. 5 g per liter of water for a drip system
