This study was conducted in 2019 order to determine the weed species, their densities and frequency of occurrences onion production areas Ankara Çorum Provinces. The surveys were carried out 78 fields, 55 23 Çorum. As a result surveys, 75 two which are parasite, belonging 28 families 64 genera, determined fields Province. with most species listed as Asteraceae (11), Poaceae (9), Fabaceae (6), C...

The essential oils from oregano (Origanum syriacum L.) and laurel (Laurus nobilis L.), their main components, namely, carvacrol, 1,8-cineole α-pinene, were tested to determine inhibitory effects on the seed germinations of three different weeds [redroot amaranth (Amaranthus retroflexus wild licorice (Glycyrrhiza glabra curled dock (Rumex crispus cutleaf ground-cherry (Physalis angulata L.)] cro...

We investigated the relationship between host-plant use by two tortoise beetles, Cassida nebulosa and C. piperata, in a field and their performance under laboratory conditions. Sixteen plant species were grown in the experimental field with C. nebulosa being observed to grow on three chenopodiaceous species (Chenopodium album, C. album var. centrorubrum, and C. ficifolium), while C. piperata gr...

Weeds are a challenge for global food production due to their rapidly evolving resistance against herbicides. We have identified chalcones as selective inhibitors of phosphoenolpyruvate carboxylase (PEPC), a key enzyme for carbon fixation and biomass increase in the C4 photosynthetic pathway of many of the world's most damaging weeds. In contrast, many of the most important crop plants use C3 p...

Four efficacy and selectivity small plot field trials were carried out in four sunflower hybrids at two localities in Middle Bohemia during 2008 and 2009 with herbicides containing the active ingredients flumioxazin and fluorochloridone. For Chenopodium album, an efficacy of 97% was found after pre-emergent application of fluorochloridone + acetochlor; the efficacy of oxyfluorfen was 88–95%; th...

Experiments were conducted to evaluate the effect of tillage systems and weed management on weed suppression and potato yield. Striptillage (ST) and conventional-tillage (CT) systems produced equal yields of Irish potato (Solanum tuberosum L.) or sweetpotato [Ipomoea batatas (L.) Lam.] when herbicide treatments were applied. Weeds in the nontreated control reduced yield of Irish potato and prev...

Alfalfa is one of the most important perennial fodder crops, and it also economical. provides first class that suitable for feeding all livestock, especially ruminants. Grass broadleaf weeds are a serious threat to quality viability alfalfa stands. Weeds can reduce nutritional value crop cause significant reductions in yield, as they compete aggressively water, nutrients, sunlight, space. In th...

Wood vinegar, a by-product of wood pyrolysis, is mostly discarded. vinegar has phytotoxic effect and could be potentially used as naturally derived herbicide for weed control. The objective this research was to evaluate the efficacy from pyrolysis apple (Malus × domestica Borkh.) tree branch wastes control weeds. concentrations required inhibit 50% motherwort (Leonurus cardiaca L.), redroot pig...

Seed germination, growth, flowering and yields of kiwano (Cucumis metuliferus E. Meyer Ex. Naudin) were examined in eastern Slavonia during 2021 growing season. The objective this study was to determine agro-morphological diversity within under different weed management practices sowing time. experiment arranged as a 3 x factorial design with three replications. Factors included options (wheat ...
