Yabancı otlar domateste (Solanum lycopersicum L.) önemli verim ve kalite kayıplarına sebep olup, hasat işlemlerini de zorlaştırmaktadır. Organik sebze üretiminde yabancı otlarla mücadele yöntemlerinden biride malçlamadır. Bundan dolayı bu çalışmayı 2020 2021 yıllarında Iğdır’da farklı kalınlıktaki malç materyallerinin domates verimi üzerindeki etkileri belirlemek amacıyla yürütülmüştür. Çalışma...

White lupine (Lupinus albus L.) is an annual legume that grown for both seeds and green biomass, but several agronomic aspects of this crop, including response to weed competition, have not been studied extensively. Field experiments over two growing seasons (2012 2016) were carried out in Orestiada, Greece, study the growth development spring-sown white under season-long competition from natur...

To study interferential effect of lamb's-quarters (Chenopodium album L.) on marigold (Calendula officinalis) yield and lamb's-quarters seed production two factorial field experiments were conducted in Tabriz, Iran, during 2010-2011. Treatments were densities of lamb's-quarters (0, 2, 4, 6 and 8 plants per meter row) and relative times of its emergence (0, 10, 20, 30 and 40 days after marigold e...

Indirect effects of insect control strategies on weed populations are important to consider when developing robust integrated pest management strategies. Weed seed predation rates were investigated in corn managed under three contrasting treatments based on control practices for corn rootworm: (1) the transgenic crop Cry3Bb Bt corn, (2) the broad-spectrum insecticide tefluthrin, and (3) no inse...

The current study aimed to investigate the chemical composition and the synergistic potential of two essential oils (EOs), as obtained from Salvia officinalis L. (SEO), and Thymus vulgaris L. (TEO). The antifungal potential was tested in vitro against Fusarium graminearum (Fg 06_17), the herbicidal effect was studied using weed seeds of Amaranthus retroflexus (ARET), Chenopodium album (CALB), E...

Natural products are one of the resources for discovering novel pesticide leads. Here, by molecular hybridization between natural enamino diketone skeleton and reported herbicide lead compound I, a series 3-(1-aminoethylidene)-6-methyl-2H-pyran-2,4(3H)-dione derivatives (APD) were rationally designed, synthesized tested herbicidal activity in greenhouse. The bioassay results showed that most ta...
