Seed production is an important element of weed population dynamics, and persistence relies upon the soil seed bank. In 2017 2018, we studied relationship between aboveground dry biomass common species their production. Weeds were selected randomly in fields, surrounded plants with a porous net to collect shed seeds during growth season. Just before crop harvest, weeds harvested, plants’ weight...

In this study, the identity and distribution of plants and the structure of their associated rhizobacterial communities were examined in an oil-contaminated site. The number of plant species that formed a community or were scattered was 24. The species living in soil highly contaminated with total petroleum hydrocarbon (TPH) (9,000-4,5000 mg/g-soil) were Cynodon dactylon, Persicaria lapathifoli...

Filamentous fungi are good producers of different extracellular enzymes. Due to this feature, some of them assumed to play an important role in the decomposition of plant and other organic materials. Several members of the class Zygomycetes are involved in different biotechnological applications, in consequence of their efficient extracellular enzyme production. Because of the increasing intere...

This study was conducted to investigate the antifungal potential and cytotoxicity of selected medicinal plants from Malaysia. The extracts from the stem of Cissus quadrangularis and the leaves of Asplenium nidus, Pereskia bleo, Persicaria odorata and Sauropus androgynus were assayed against six fungi using p-iodonitrotetrazolium-based on colorimetric broth microdilution method. All the plant ex...

Despite an extensive history of research into herbicide resistance in New Zealand maize, some aspects remain understudied. Herbicide was first detected the 1980s maize crops, with atrazine Chenopodium album L. and Persicaria maculosa Gray. Since then, has also developed to dicamba, last five years Digitaria sanguinalis (L.) Scop. populations have been reported be resistant nicosulfuron. Here we...

Sunflower is the most important oil crop in Republic of Croatia. In last two decades, it has been grown on average 33,506 ha with a grain yield 2.66 t/ha. Weeds represent one causes biotic stress, and their action reflected competition for nutrients, water, light space. The weed flora sunflower crops Croatia extremely diverse, we will often meet: Polygonum persicaria L., lapathifolium Ambrosia ...

The experiments were conducted in 2017-2018 on soybean (Glycine max L.) three climatic regions of Russia (Altai Region, Krasnodar Region and Astrakhan Region) to evaluate efficacy herbicide diclosulam (WG, 750 g/kg). Treatments included diclosulam: 1) applied preemergence (PRE) - 18.75 37.5 g i.a. ha-1; 2) postemergence (POST) at 1-3 leaves soybeans (BBCH 11-13) 11.25 22.5 ha-1. Monocotyledonou...
