Ragweed parthenium is an herbaceous annual or short-lived perennial weed. It is difficult to manage in many fields due to known resistance to commonly used herbicides. There are a limited number of modes of action that can be used in some vegetable and berry crops. This new 4-page publication of the UF/IFAS Environmental Horticulture Department provides management recommendations. Written by Nathan S. Boyd, Shaun M.

SummaryOsteoporosis in men is increasingly recognized as an important public health problem but affected patients are still under-diagnosed and -treated. As in women the diagnostic and therapeutic strategy has to be adapted to the individual case. In the practical management it is very important to detect possible causes of secondary osteoporosis, to explain the possibilities of basic therapy counteracting individual risk factors and communicate that osteoporosis is a chronic disease and adherence to a long-term treatment is crucial. In established severe osteoporosis a careful analgesic therapy is important to avoid further bone loss related to immobility. In elderly men with increased risk of falling insufficient Vitamin D supply or impaired activation of Vitamin D due to renal insufficiency must be taken into consideration. Specific medications available today for the treatment of male osteoporosis comprise among antiresorptive drugs the bis phosphonates alendronate, risedronate and zoledronic acid. Denosumab, the first biological therapy is approved for men with androgen deprivation therapy for prostate cancer. An important advantage of this potent antiresorptive drug is the increased adherence due to the comfortable application by sixmonthly subcutaneous injections. Study results from the 2-year multi-center randomized controlled ADAMO-Study will very soon allow the use of denosumab in all types of male osteoporosis. Teriparatide, the 34 N-terminal amino acid sequence of parathyroid hormone was approved for men with osteoporosis as an anabolic agent based on proven efficacy by different studies. Among drugs with other modes of action the D-hormone pro-drug alfacalcidol can be used in men alone or in combination with the advantage of pleiotropic effects on calcium absorption, parathyroids, bone and muscle. Recently also Strontium-ranelate was approved for male patients with the limitation to exclude men with clinical relevant cardiovascular risk factors. In general the possibilities to treat male osteoporosis have considerably improved during recent years. Today there is a choice of a spectrum of drugs from mild to strong potency with different modes of action on bone turnover to design strategies for individual male patients.

Argentina is experiencing an expansion of soya and maize cultivation that is pushing the agricultural frontier over areas formerly occupied by native Chaco forest. Subsistance farmers use this dry forest to raise goats and cattle and to obtain a broad range of goods and services. Thus, two very different and non-compatible land uses are in dispute. On the one hand subsistance farmers fostering an extensive and diversified forest use, on the other hand, large-scale producers who need to clear out the forest to sow annual crops in order to appropriate soil fertility. First, the paper looks at how these social actors perceive Chaco forest, what their interests are, and what kind of values they attach to it. Second, we analyze the social-environmental conflicts that arise among actors in order to appropriate forest’s benefits. Special attention is paid to the role played by the government in relation to: (a) how does it respond to the demands of the different sectors; and (b) how it deals with the management recommendations produced by scientists carrying out social and ecological research. To put these ideas at test we focus on a case study located in Western Córdoba (Argentina), where industrial agriculture is expanding at a fast pace, and where social actors’ interests are generating a series of disputes and conflicts. Drawing upon field work, the paper shows how power alliances between economic and political powers, use the institutional framework of the State in their own benefit, disregarding wider environmental and social costs.

Red Currant

The main goal of the scientific institution was and remains to improve the assortment of fruit and berry crops for the development of domestic horticulture. Black currant breeding at VNIISPK was started by A.F Tamarova and continued by the doctor of agricultural Sciences T.P.Ogoltsova and doctor of agricultural Sciences S.D. Knyazev. A long-term breeding program has been developed. The main goals of the program are to create black currant cultivars with continuous resistance to diseases, first of all powdery mildew, as wells resistance to pests, i.e. bud mite. As a result of the long-term work, over 40 black currant cultivars have been developed, 14 of them are zoned. Red currant breeding was led by the candidate of agricultural Sciences L.V. Bayanova; since 2001 the work has been continued by the candidate of agricultural Sciences O.D. Golyaeva. ‘Heinemanns Rote Spӓtlese’, the descendant of R. multiflorum Kit., was involved in the red currant breeding for the first time in Russia. On its genetic basis, a series of late maturing cultivars with long and dense racemes was created. At the Institute, in total 21cultivars of red currants have been developed, 13 of them are zoned. At present, red currant cultivars make up 25.5% of the zoned assortment in Russia. The first research on gooseberries was stated by V.P. Semakin and A.F Tamarova; since 1992 the systematic gooseberry breeding has been carried out by the candidate of agricultural Sciences O.V. Kurashev. On the basis of Grossularia robusta, we have created gooseberry forms that are resistant to powdery mildew and leaf spots. These forms are highly productive, weakly thorned, having bush habit suitable for mechanized harvest. The result of breeding activities was the transfer of 6 gooseberry cultivars to State agricultural testing: ‘Solnechny Zaychik’, ‘Nekrasovsky’, ‘Yupiter’, ‘Zemlianichny’, ‘Moryachok’ and ‘Discovery’.

Phytosanitary Measures

In the production of planting material, it is important to choose a healthy, highly productive source material, with typical varietal characteristics, and, if necessary, their disinfection), as well as reliable protection against dangerous pests at further stages of cultivation. This requires a scientifically based methodological approach and phytosanitary measures in several areas. First of all, it is required to study and classify in detail hazardous pests and pathogens, select methods for accounting and identifying in accordance with their degree of danger and the quality category of planting material. Apply comprehensive measures to prevent the entry of pests in the territory of growing planting material and timely eliminate the centers of potential threat.
