Plot-scale field studies were conducted to evaluate the efficacy of steam for the control of cropland weeds in comparison with common herbicides. Weed densities, biomass, or emergence after treatment were measured. Steam (3,200 kg/ha, energy dosage equivalent to 890 kJ/m2, speed of 0.8 m/s) and glyphosate (560 g ai/ha) gave similar control (. 90%) of seedling common lambsquarters and seedling r...

Eighteen volatile monoterpenes, which are among the major constituents of essential oils from plants, were screened for phytotoxicity to several crop and weed species. Several monoterpenes containing an oxygen function severely inhibited germination of four different annual weeds while concurrently displaying little effect on soybean germination. Soybeans varied in their sensitivity to various ...

Seed germination is the key step for successful establishment, growth and further expansion of population especially for alien plants with annual life cycle. Traits like better adaptability and germination response were thought to be associated with plant invasion. However, there are not enough empirical studies correlating adaptation to environmental factors with germination response of alien ...

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...

Moving towards sustainable agriculture implies exploring the interconnections between farming and the environment, and soil is a key component of sustainability. Mulching is one of the methods to protect and enhance the productivity of the soil. We studied here the effect of mulching applied to mandarin tree rows for weed control in two localities near Tortosa, Spain, to compare its performance...

Examples of atypical structure the embryonic apparatus indicator plants in Donbas are highlighted. Many years experience conducting phytoindication experiments (1998–2022) made it possible to identify accounting sites with contrasting geochemical characteristics and monodominant ingredient pollution. Registered abnormalities considered as variants extreme structural polymorphism natural flora u...

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...

A total of 231 different soil Streptomyces isolates were recovered from 16 different locations in North Jordan. They were assessed for their phytotoxic activity on seeds of cucumber (Cucumis sativus L.) and ryegrass (Lolium perenne L.) placed adjacent to a 2 cm wide Streptomyces culture strips grown at 28C degrees for 3 weeks on starch casein nitrate (SCN) agar. Phytotoxicity was ascertained on...
