**2. Perspectives on the potential of plant essential oils as green biopesticides in agricultural 4.0**

Plant essential oils (Plant Eos) were used as biopesticides in agricultural systems for a long time. In the case of local usage, the plant materials were extracted by using differently traditional extraction techniques that the quantity and quality of bioactive essential oil compounds (EOCs) were less [2]. Therefore, the local knowledge will be upgraded for commercial production. Natural products will be continually accepted and used by farmers in the epidemic areas. A competitive challenge for commercial producers has high competition and follows by the trends of environment and healthy consumption under the world market. The environmental contamination and human health problems caused by the overuse of chemical pesticides have been reported and published in recent years. The use of chemical pesticides was the first choice for pest management, which has been increasingly apparent because of the high efficiency, specificity, and fast-acting on the target insect vectors [3].

The phenomenon, which related to the increasing use of chemical pesticides in agriculture, was the result of the successful breeding of new high-yielding rice varieties in the green revolution period [4]. The various innovative agricultural technological achievements over the years of synthetic chemical products were shown a fast action and specific effect on target organisms but have developed resistance against them. Thus, this awareness regarding problems had been significantly important to the agricultural management. Especially in research development pertained to avoid chemical resistance of insect pests by the green innovative technology and integrating sustainability principles [5]. In this context, biopesticides derived from the different plant species have the potential for solving problems as well as developing natural commercial products for safe crop productivity increasing. Biopesticides are becoming a bright alternative replacement to chemical pesticides due to the significantly growing agricultural supply chain of both consumers and producers. However, there are limitations of plant EO activities such as rapid conversion and degradation by the various factors under field conditions.

Nowadays, despite considerable research and development effort on the plant EO properties and their active compound, yet their commercial products have few appeared in the global marketplace. As a result of this, it cannot be denied that such issues are only achieved concrete results at the policy level, which resulted from the regulatory commercialization barriers. Therefore, the status and potential of plant EOs as green biopesticides should be researched and developed with innovative technology under the three concepts including social acceptability,

economic viability, and environmental stewardship (**Figure 1**) [6]. As a result, the high-quality products will be created with low cost and easy to use in the operation model of sustainability Agriculture 4.0.
