“…Agricultural biodefensives include bioherbicides, biofungicides, and biopesticides. Bioherbicides use organic products, such as fungus extract [16], oil extract [23], fruit enzyme [15], and other biological materials. Biofungicides are a group of agricultural biodefensives based on competing fungi that do not affect the development of the agricultural product [24].…”

Population growth and the need for increased agricultural productivity pose a global problem. Therefore, the development of green compounds to ensure agricultural sustainability becomes an urgent necessity. Surfactant compounds hold significant commercial importance due to their diverse industrial uses. However, the synthetic origin of these agents limits their commercial application due to their toxicity. As a result, extensive research has focused on the production of microbial-originated green surfactants, known as biosurfactants, over the past fifteen years. These biomolecules not only offer a green alternative for agriculture but also exhibit reduced toxicity and excellent stability under specific environmental conditions. Biosurfactants can lower surface tension more effectively than synthetic surfactants. With properties such as detergency and foam formation, biosurfactants are suitable for various agricultural applications, particularly in pesticide and agrochemical formulations. They can function as biopesticides to manage pests, pathogens, phytopathogenic fungi, and weeds due to their antimicrobial activity. Moreover, plants can benefit from biosurfactant molecules and the microorganisms as nutrients. They can also aid efficiently in the distribution of micronutrients and metals in the soil. They also stimulate plant immunity and are utilized for soil hydrophilization to ensure proper moisture levels and uniform fertilizer distribution. This review aims to provide valuable insights into the role and properties of biosurfactants as agricultural adjuvants, fostering the development of sustainable formulations to replace chemical surfactants used in pesticides.

Recent extracts of various plant species and types such as citrus [8], cardoon [9], essential oils[10], and aerial spontaneous plants [11] were also exploited for bioherbicide application. The main active ingredients of bioactive substances from plants extraction are supported by phenolic compounds [12,13].…”

Thermal anaerobic hydrolyzation process on rice husk with higher lignin content produced organic complexes constituents including phenolic groups. Phenolic groups expose herbicide effects on growing vegetations, where the process in nature mainly require anaerobic condition. The degradation rate in nature is very slow with very low concentration availability. Thermal hydrolyzation is an appropriate choice to produce phenolics herbicide for sustainable pesticide management and application. This study aimed to identify the potency of rice husk extract by thermal hydrolyzation process as an organic herbicide to control terrestrial weeds. The hydrolyzation was processed in 60-90 bars and 280±20 °C for 30±10 minutes. The existence of the phenolic groups in the hydrolysate was considered for generic active ingredients to control weed in the terrestrial ecosystem. Its damage impact was tested on Borreria alata, Eleusine indica, Cyperus kyllingia, Paspalum conjugatum, Asystasia intrusa, and Axonopus compressus. The assay covered the growth at pre-emergence, early post-emergence, and post-emergence growing stages. The rice waste hydrolysate was capable to suppress the growth of the weed growth especially at the pre-emergence stage at 30-64%, and at early post-emergence stages at the suppressing rate of 77-100%. However, the suppressing affectivity is lower at the post-emergence stage which only 17-25%.

“…The gradual accumulation or incorrect disposal of these wastes may cause environmental problems [10]. Recent studies reported that some agro-industrial wastes, such as orange peel, olive oil mill wastes and mango leaves, have allelopathic effect and could be utilized in weed control as natural products [11,12,13,14].…”

Phenolic compounds are considered one of the most important secondary metabolites categories in plant that involved in allelopathic effect. Allelopathy is a chemical interaction between plants and could be defined as the stimulatory or inhibitory effects of a plant on the growth of another plant through the release of secondary compounds. The phenolic compounds, in orange juice peel waste (ORPW), olive oil mill waste (OLMW) and mango leaves waste (MLW), were extracted, then identified and determined by HPLC. The allelopathic effect of ORPW, OLMW and MLW aqueous extracts, at successive concentrations, was examined on germination and growth of two weed species (Phalaris minor Retz. and Malva parviflora L.) in petri dishes and pots bioassays. The main detected phenolic compounds were ferulic, chrysin, sinapic, p-hydroxybenzoic, quercetin and rosmarinic in ORPW extract, vanillic, cateachin, rutin, protocatechuic and gallic in MLW extract, and gallic, pcoumaric, protocatechuic, p-hydroxybenzoic, vanillic and ferulic in OLMW extract. The aqueous extracts of ORPW recorded the highest concentration of phenolic compounds and were the most effective in inhibition the germination and growth of both weed species followed by MLW and OLMW in petri dishes and pots trails. It can be concluded that the aqueous extracts of ORPW and MLW wastes have high contents of phenolic acids and could be utilized in controlling weeds as natural herbicides.
