METARHIZIUM ANISOPLIAE IS USED IN AGRICULTURE FOR THE PURPOSE OF BIOPEST CONTROL.

Biological pesticides One kind of entomopathogenic fungus is called metarhizium anisopliae, and it is capable of infecting insects that come into touch with it. After the spores of the fungus have attached themselves to the surface of the insect, germinated, and started to develop, they will then pierce the exoskeleton of the insect and begin to grow extremely quickly within the insect, which will ultimately result in the death of the insect. When infected insects come into touch with other insects, the fungus spreads to those insects and causes them to become infected. In terms of their mechanism of action, products of the metarhizium anisopliae fungus are harmful to pests. Conidia of the metarhizium anisopliae fungus are able to adhere themselves to the internodes of the epidermis of the host insect with relative ease. In the presence of an appropriate temperature and humidity, the conidia will germinate, resulting in the production of bud tubes and the formation of hyphae. Enzymes that are capable of dissolving chitin, which break down the body walls of insects, are secreted by mycelia. After penetrating the epidermis of the host, hyphae progressively go deeper, infiltrating the adipose tissue and muscle of insects. This process is facilitated by the pressure exerted by bacteria on the host throughout the invasion process. As the mycelium grows inside the body of the insect, it ultimately results in the insect’s demise. Yellow-brown dots may be detected on the body wall of host insects when metarhizium anisopliae detects them for the first time. Within insects, neurological abnormalities start to manifest themselves as a result of the activity of the metarhizium toxin. In the end, larvae will cease eating, their reaction to stimuli will lessen, and they will finally die. Once the individual had passed away, the body became hard, and the hyphae that were contained inside the worm started to expand to the exterior. In a short amount of time, a coating of white hyphae was seen covering the body. Conidial stalks and conidia began to grow on the hypha two or three days after the first hypha was produced. Green or a dark green color appears on it. techniques of application foliar spray: the product should be sprayed on the growing plants using hand, ground, or aerial spray equipment. This is done to prevent hoppers and pests from infesting the plants. soil application (root grubs and vine weevils): metarhizium anisopliae may be sprinkled about the root zone and integrated into the soil either manually or by watering plants. This is an effective method for controlling root grubs and vine weevils. After being filtered via the right filters, it may also be absorbed into the soil by drip irrigation systems or other similar methods. Applications should be submitted at least once per week for a period of four weeks when the frequency of application is increased. Applications should be performed every 1015 days for greenhouse pest issues, according to the recommendations. It is essential that the monitoring of insect populations serve as the foundation for all treatments. Foliar spray dosage: 2.5 kilogrammes per hectare in 500 liters of water, which is equivalent to 5 grams per liter of water. The crop canopy is a factor that determines the spray volume. 2.5 kilogrammes per acre applied to the soil. 5 grams of water per liter for the drip system
