“…Another species of the Thymus genus, T. eigii, showed significant herbicidal activity against L. sativa, Lepidium sativum L., and Portulaca oleracea L., with 0.5 mg/ml oil completely suppressed the seed germination of all the tested species (Zeynep et al,, 2018). Sara et al (2019) investigated the herbicidal action of T. fontanesii EO and found 0.03% T. fontanesii oil inhibited the seed germination by 100% on Sinapis arvensis, Avena fatua, Sonchus oleraceus, and Cyperus rotundus.…”

Allelopathic, Phytotoxic, and Insecticidal Effects of Thymus proximus Serg. Essential Oil and Its Major Constituents

The chemical profile of Thymus proximus essential oil (EO) and its allelopathic, phytotoxic, and insecticidal activity was evaluated. Carvacrol, p-cymene, and γ-terpinene were detected as the major components of the EO, representing 85.9% of the total oil. About 50 g fresh plant material of T. proximus in a 1.5-L air tight container completely inhibited the seed germination of Amaranthus retroflexus and Poa anuua. Meanwhile, the EO exhibited potent phytotoxic activity, which resulted in 100% germination failure of both the test species when 2 mg/ml (for A. retroflexus) and 5 mg/ml (for Poa annua) oil was applied. The EO also triggered a significant insecticidal activity on Aphis gossypii with a LC50 value of 6.34 ppm. Carvacrol was identified as the main active compound responsible for both the plant suppressing effect and the insecticidal activity of the EO. Our study is the first on the allelopathic, phytotoxic, and insecticidal activity of T. proximus EO, and the determination of the responsible compound, which indicated their potential of being further explored as environment friendly biopesticides.

“…In this manner, lemon essential oil up to 3% showed phytotoxic of leaves and roots on corn plant (Hollingsworth 2005). Thyme and cotton lavender EOs seem promising herbicides due to their lower phytotoxicity to major cereal and vegetable crops (Benchaa et al 2019). The greatest herbicidal activity of EOs containing high concentrations of carvacrol, carvone, thymol, linalool, and terpinen-4-ol causes the highest reduction of the weed Bristly foxtail (Koiou et al 2020).…”

The fumigant pesticide methyl bromide (MB) is no longer used in most countries due to its carcinogenic effects. It is followed by carbon bisulfide and chloropicrin which are the most effective liquid synthetic chemicals in pesticide formulations. They are converted to gas to penetrate soil particles and eliminate plant pests such as insects, weeds, and causal plant diseases of viruses, bacteria, fungi, and nematodes under greenhouse, field and storage conditions. These fumigants are non specific pesticides and highly hazardous to humans, environmental resources, and deplete the ozone layers. Furthermore, increasing the cost of crop production by inceasing the amount of pesticides treatments was increased the cost of research on the alternatives of green pesticides from eco-friendly agents, natural organic soil amendments of organic wastes, green manure, biofumigation crops, compost, and essential oils, as well as formulations, are examples of this. Organic fumigants that are non toxic, non-residual, highly degradable and decomposable are available as eco-friendly alternatives to chemical pesticides to manage soil borne pests and diseases of plants. This article summarizes the development of applicable eco-friendly formulations which use natural organic materials to disinfest soil in order to reduce plant diseases caused by soil--borne pathogens.

“…While synthetic herbicides can have negative impacts on both the environment and health of humans. As a result, natural substances such as essential oils are becoming increasingly popular for weed management (Benchaa et al, 2019). Using a method that can quickly detect powerful chemical components obtained from natural sources is essential to improving the efficacy of new herbicidal chemicals.…”

There is an urgent need to develop eco-friendly and sustainable pesticide formulations due to the harmful properties of synthetic pesticides on both environment and human health. Essential oils are mixtures of volatile oils made from medicinal plants as a secondary metabolite, have proven efficacy against pests and pathogenic fungus. Nonetheless, a number of variables, including plant species, geographic location, environmental factors, agricultural practices, and extraction methods, have an impact on the chemical makeup of essential oils. The increasing number of studies of research investigating the nematocidal, acaricidal, herbicidal, insecticidal, and antibacterial properties of essential oils highlight their potential as environmentally friendly, long-lasting biopesticides. The EOs have the potential to break down into harmless compounds and have minimal negative impacts on non-target organisms. However, despite their potential, there are few commercially available biopesticides that utilize EOs. This is because there are various challenges that must be addressed, including the instability and reduced effectiveness of EOs under environmental conditions. An overview of recent studies that investigate the challenges faced in using EOs as biopesticides and current research on their application is given in this review article.
