eBooks de Enfermedades y plagas

Estudio de la forma en que la ciencia agrícola puede ayudar a aumentar las cosechas y a resolver un problema que no sólo es de México: el bajo incremento de la producción agrícola en las últimas décadas. A los profesionales no les gustan el olor de los insecticidas, el peligro de sus efectos, el precio, ni la idea de emplearlos, pero saben que su uso juicioso ayuda a obtener mejores cosechas. Este libro, aunque abarca varios campos, se centra en los problemas que presentan el combate a las plagas y el uso de plaguicidas; esto es, la agroquimica.

Among the many challenges facing the contemporary smallholder who keeps livestock and grows his own food, is how to deal with the various pests that are capable of decimating crops, degrading pasture, stealing produce, contaminating animal feed and killing valuable livestock. This book provides the smallholder with the knowledge and the information about the skills to meet this challenge in an effective and humane way.Considers all the major pests faced by smallholders including rats, house and field mice, grey squirrels, moles, rabbits, deer, foxes, mink, wood pigeons, crows and rooks. Discusses each pest in detail, arguing that it is essential for the smallholder to understand their characteristics and behaviour in order to control them successfully.

Covers traps, poisons, air rifles, dogs, ferrets, electric fencing, bird scarers, wildlife deterrents and repellents, automatic bird feeders, and polytunnels and cloches.

An invaluable and well-illustrated book that provides the smallholder with the knowledge required to deal efficiently and humanely with the various pests that present a constant challenge. Essential reading for small-scale farmers, smallholders and those with large gardens attached to properties in the countryside. Superbly illustrated with 146 colour photographs.

If you are a gardener, groundsman, smallholder or farmer and have a mole problem, then this book will be of enormous help to you. Pest-control books normally only devote a paragraph or two to moles and rarely cover the subject in detail. This volume is very different and is probably one of the most comprehensive books ever written on mole trapping. Throughout the book, Jeff Nicholls, a professional mole catcher, reveals his enormous respect for the mole and emphasizes the absolute need to control these rarely seen animals using humane and traditional methods that have been proven to work effectively. At the outset the author discusses the natural history of the mole and explains its characteristics and behaviour, an understanding of which is essential if successful catching techniques are to be applied. He then discusses in detail the traditional and humane methods he uses in different terrain and weather conditions, considers how to locate mole runs, describes all the different types of traps that can be employed and explains how to set the traps correctly.

This comprehensive and practical book, produced specifically for shoots and conservationists, provides a basic guide to all aspects of control. It explains which species can be controlled and by what means. There is detailed guidance on shooting, snaring, trapping, the use of dogs and humane dispatch. The law governing pest species is covered in detail, particularly in regard to the general licences which are frequently misunderstood, occasionally leading to prosecution. Detailed instructions are provided on the effective and legal use of snares and traps with photographic sequences to show how they should be sited and set. This will be invaluable to those who enforce wildlife law and need to distinguish between legal and illegal methods of control.
