The present application claims priority to Indian Patent Application number 202321062645 filed Sep. 18, 2023. The aforementioned application is hereby incorporated by reference in its entirety.
The present invention relates to synergistic botanical based bio-stimulant, bio-acaricidal compositions for controlling pests, increasing plant growth and crop yield by improving plant physiological process like photosynthesis and other essential metabolic process in plants/crops that is cost effective and environment friendly. The present invention also relates to process for preparation of said composition.
Agricultural and horticultural crops are attacked by various pests every year, the most important of which are insects, mites, nematodes and gastropod molluscs. They can adversely affect agricultural production and the natural environment. They can cause problems by damaging crops and food production, infesting livestock, and causing nuisance and health hazards to humans. The damage is caused both by direct damage to plants and by indirect effects of the fungal, bacterial or viral infections they transmit.
Major agriculture pests such as several species of ticks and mites can have disastrous effects on agriculture. There are hundreds of different species of mites, which are tiny arthropods that belong to the Tetranychidae family and are classified as Arachnids. Species of mites include Tetranychus urticae, Tetranychus cinnabarinus, Panonychus ulmi, and Panonychus citri, go by the common name “red or yellow mites”. Controlling red and yellow mite infestations on crops is crucial because, if left unchecked, they will have disastrous effects. Ticks and mites are important vectors of disease-causing pathogens in humans, wildlife and domestic animals and wreak havoc on agricultural products all over the world.
Chemical pesticides such as acaricides are used to kill pests such as ticks and mites. Acaricides include chlorinated hydrocarbons (e.g., dichlorodiphenyltrichloroethane; DDT), organophosphorous compounds (e.g., Diazinon), carbamates (e.g., carbaryl), pyrethroids (e.g., permethrin, flumethrin), formamidines, and avermectins. The pyrethroids are one of the most effective pesticides used for tick control.
Acaricides are effective in controlling or killing crop pests. However, with repeated application, pests develop tolerance and resistance to these chemical pesticides. Ticks have been found to be resistant to cyclodiene insecticides, chlorinated hydrocarbons, organophosphorus insecticides, and pyrethroid insecticides. They also cause a number of environmental problems, such as pesticide residue and pest resurgence. The use of chemical acaricides to control pests results in toxic chemicals being released into the environment, which are hazardous to both humans and the environment. Furthermore, these synthetic chemicals can frequently persist in the environment indefinitely. However, these chemical pesticides are widely used to maximize crop productivity, resulting in negative environmental effects that are harmful to humans and other animals.
In addition to these, chemical pesticides are the main cause of wide range toxicity to humans, reflecting in an increase in the number of cancer cases globally. Along with people paying attention to environmental and health issues on a daily basis, using safer bioinsecticides on crops has become a top priority to reduce the use of chemical pesticides.
Bio-pesticides are safer alternatives to chemical pesticides as they are efficient to use, have low toxicity, leave little residue, and are easy to decompose. They are safe against non-target organisms, and do not disrupt natural ecological defense systems.
The use of botanical based acaricides can effectively reduce chemical based acaricides consumption; therefore, the research and development of botanical pesticides that use plant extracts and chemical pesticides in combination has become a study hotspot of Pesticide Science in recent years.
CN102204555 discloses an insecticidal and acaricidal compound composition, comprising effective ingredients of a biopesticide lepimectin and bifenazate, and a weight ratio of the former to the latter is 0.1-50:80-1. It can be used for controlling damages caused by mites, insects with piercing-sucking mouthparts in fruit trees, crops and vegetables.
EP1301079A2 discloses botanical acaricides for controlling plant-infesting acari with plant extracts providing the advantages of minimal development of resistance thereto, minimal toxicity to mammals, minimal residual activity and environmental compatibility.
