Insecticidal joint action of ternary extract mixtures of four species of tropical plants against Plutella xylostella andCrocidolomia pavonana. The diamondback moth (DBM), Plutella xylostella, and the cabbage head caterpillar (CHC),Crocidolomia pavonana, were two main pests of cruciferous vegetable crops. Among the viable alternative ingredients thatcould be utilized to control those two pests were eco-friendly botanical insecticides. This study was conducted to evaluatethe joint action of ternary extract mixtures of four tropical plant species, i.e. Piper aduncum (Pa), Piper retrofractum (Pr),Sapindus rarak (Sr), and Tephrosia vogelii (Tv), against DBM and CHC. Results of leaf-residue feeding bioassays showedthat based on co-toxicity ratio at both LC 50 and LC levels, ternary mixtures of Pa extract with Sr and Tv extracts at concentrationratios of 1:5:1, 1:5:2, and 2:5:1 indicated synergistic joint action on DBM larvae. A mixture of Pa, Sr and Tv extracts at a ratio of2:5:1 was also synergistic to CHC at both LC level but antagonistic at the LC 95 50 95 and LC 95 levels. This mixture at the 1:5:1 ratio was synergistic on CHC at the LC level whereas at the 1:5:2 ratio was antagonistic to CHC at both LC levels. Furthermore, ternary mixtures of Pr extract with Sr and Tv extracts at the three concentration ratios were synergistic to CHC. Thus, ternary mixtures of Pa or Pr extract with Sr and Tv extracts at appropriate concentration ratios are potential alternatives for the control of DBM and CHC.

A study of the glucosinolate content of seven common cruciferous vegetables showed wide variation between crops and, in some cases, between cultivars. High progoitrin levels were found in rutabaga (Brassica napobrassica Mill.). Glucosinolates that hydrolyze to give ionic thiocyanate were present in all samples analyzed. Rapine broccoli (B. oleracea var. italica Plenck) had the highest content of thiourea derivative.

The 19Th Century

The cruciferous weed Hesperis matronalis, dame's rocket (Brassicaceae), is an introduced Eurasian garden plant that began to escape shortly after its introduction to North America in the 19th century. It has gradually become naturalized across Canada and the United States, and has become invasive. It is not a major weed of crops, but is widespread in natural and conservation areas, particularly in thickets, open woodlands, forest margins and along streambanks, in parts of eastern and southern Ontario and western Quebec in Canada, and in New England and the midwest in the United States. In these habitats it can crowd out native vegetation and subsequently reduce biodiversity. Serving as an alternate host to a number of viruses, the species has the potential to infect cruciferous vegetable crops and garden plants. Despite its invasive potential, it continues to be sold at garden centres in both Canada and the United States.

Introduction: greenhouses need microclimate control systems to grow agricultural crops. The method of carbon dioxide injection, which is currently used by agricultural companies, causes particular problems. Co-generation power plants may boost the greenhouse efficiency, as they are capable of producing electric energy, heat and cold, as well as carbon dioxide designated for greenhouse plants.Methods: the co-authors provide their estimates of the future gas/electricity rates growth in the short term; they have made a breakdown of the costs of greenhouse products, and they have also compiled the diagrams describing electricity consumption in case of traditional and non-traditional patterns of power supply; they also provide a power distribution pattern typical for greenhouse businesses, as well as the structure and the principle of operation of a co-generation unit used by a greenhouse facility.Results and discussion: the co-authors highlight the strengths of co-generation units used by greenhouse facilities. They have also identified the biological features of carbon dioxide generation and consumption, and they have listed the consequences of using carbon dioxide to enrich vegetable crops.Conclusion: the co-authors have formulated the expediency of using co-generation power plants as part of power generation facilities that serve greenhouses.
