Monitoring of phytopathological situation in crops is the basis for biological justification need protective measures, allowing to obtain a yield close potentially possible. The results monitoring spring wheat varieties are presented paper. Studies were carried out 2019–2021 laboratory phytopathology and experimental field Institute Plant Protection. Standard methods used during work. main crit...
Frankliniella spp. (Thysanoptera: Thripidae) thrips damage a variety of crops, feed on a broad range of hosts, and often migrate into cropping systems from adjacent vegetation. To determine potential sources of Frankliniella spp. thrips on crops, annual cycles of abundance of Frankliniella occidentalis (Pergande), Frankliniella fusca (Hinds), Frankliniella bispinosa (Morgan), and Frankliniella ...
The effects of the management of genetically modified herbicide-tolerant (GMHT) crops on the abundances of aerial and epigeal arthropods were assessed in 66 beet, 68 maize and 67 spring oilseed rape sites as part of the Farm Scale Evaluations of GMHT crops. Most higher taxa were insensitive to differences between GMHT and conventional weed management, but significant effects were found on the a...
A postal survey conducted of 172 farms in the intensive farming areas of East and Northeast Scotland revealed that one in four farms considered that there was a serious rabbit {Oryctolagus cuniculus L.) problem. Although a wide range of crops was subject to damage, winter cereals and winter oilseed rape were particularly affected by grazing, especially in the winter and spring periods. Two-thir...
In order to evaluate the effects of cover crops on reduced weed biomass in hybrid sunflower an experiment was carried in the research stations, Natural Resources Medicinal Plants (Samian_Ardabile) with 3 replicates in 1390-1391. The first factor was considered three type of cover crops, winter rye, spring barley, winter wheat with 2 control treatment, second factor was mulch management at two ...
Post-Conservation Reserve Program (CRP) land may provide an excellent opportunity to satisfy certified organic crop production requirements. However, conversion of CRP or long-term pastureland to certified organic production will require tillage because the use of herbicides is prohibited in organic production. Our objectives were to evaluate stand establishment, weed competition, yield, and gr...
