BACKGROUND Spray volume can influence the amount of free water on the leaf surface and subsequently the ability of entomopathogenic nematodes (EPNs) to move. In this study, an investigation was made of the effect of spray volume (548, 730 and 1095 L ha(-1) ) on the deposition, viability and infectivity of EPNs against Galleria mellonella on savoy cabbage, cauliflower and leek. RESULTS Increas...

in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...

• Neural network-based growth models are able to forecast plant growth. GANs produce realistic, reliable, and reasonable images of future stages. Generated all phases allow the derivation phenotypic traits. Increased explainability compared direct prediction individual parameters. Farmers frequently assess performance as basis for making decisions when take action in field, such fertilization, ...

This study aims to determine the effect of combination NPK fertilizer and bean sprout extract (BSE) on growth yield cauliflower plants right dose extract, so as provide maximum results in lowlands. The experiment was carried out Pusakanagara District, Subang Regency, West Java Province. With an altitude 15 m above sea level, air temperature ranges from 270C–300C. October December 2022. used exp...

Our research groups have previously published a study estimating the bottleneck size of Cauliflower mosaic virus (CaMV) during host plant colonization [1]. Two methods were used in that study, both based on the temporal evolution of neutral marker frequencies; one uses estimates of FST, and the other tracks changes in marker frequency variance over time. Here we report that (i) the variance-bas...

Swede midge (Contarinia nasturtii Keiffer) is a serious gall-forming insect pest of cruciferous plants in Europe and southwestern Asia. In North America, it was first identified in Ontario, Canada, in 2000 and in Niagara County, New York, US, in 2004. The insect is now rapidly spreading in Canada and the US. To date, infestation of C. nasturtii has been confirmed in 46 counties in Canada. The U...

This paper gives an overview of the epidemiological data concerning the cancer-preventive effect of brassica vegetables, including cabbage, kale, broccoli, Brussels sprouts, and cauliflower. The protective effect of brassicas against cancer may be due to their relatively high content of glucosinolates. Certain hydrolysis products of glucosinolates have shown anticarcinogenic properties. The res...

Black rot caused by Xanthomonas campestris pv. campestris (Xcc) is a very important disease of cauliflower (Brassica oleracea botrytis group) resulting into 10-50% yield losses every year. Since there is a dearth of availability of resistance to black rot disease in B. oleracea (C genome), therefore exploration of A and B genomes was inevitable as they have been reported to be potential reservo...
