Abstract:

Okra (Abelmoschus esculentus) is a popular tropical and subtropical vegetable, grown on thousands of hectares in Pakistan, but yield is low due to a variety of factors, including the presence of insect pests and pathogen-borne illnesses. Among insect pests, two spotted red spider mite, Tetranychus urticae is a phytophagous mite that can affect plant physiological processes, causing severe economic losses of various agricultural and horticultural crops all over the world including Pakistan. An approximately, 30% of the total cost of pesticides used in some major crops. Chemical control is the most common strategy used to handle this pest on crops especially okra. Chemically manufactured acaricides, on the other hand, have a variety of drawbacks, including pest resistance, incompatibility with natural predators, phytotoxicity, pollution, and health hazards. There was need to adopt an alternative strategy such as botanicals to control this pest and to minimize environmental pollution in the country. To check the toxicity of plant-based products against T. urticae, the current study was conducted in laboratory during 2020. The order of ovicidal and adulticidal toxicity based on slope values and LC50 was neem A. indica > N. tabacum > D. alba. The lowest mortality (3.089 ± 0.0006) of adults was recorded by the application of D. alba while highest on A. indica (2.800 ± 0.0009). Mortality data and the slope values showed that the most toxic plant extract against eggs was A. indica (LC50 = 2.523%) followed by N. tabacum (LC50 = 3.789%) and D. alba (LC50 = 3.854%). The current ecofriendly technique can be manufacture at farm level by okra producers which minimize the mite attack on their crops
