The aim of the research was analysis of rice producers’ perceptions of participatory communication in the use of integrated pest management (IPM). Research population was consisted of rice producers in the west of Mazandaran province (N=16126), whose 187 ones were selected using Cochran’s formula. Data were gathered by systematic random sampling method. The instrument for data collection was a ...

Several potential cover crops were evaluated for their susceptibility to Meloidogyne arenaria race 1, M. incognita race 1, and M. javanica in a series of five greenhouse experiments. No galls or egg masses were observed on roots of castor (Ricinus communis), cowpea (Vigna unguiculata cv. Iron Clay), crotalaria (Crotalaria spectabilis), or American jointvetch (Aeschynomene americana). Occasional...

Maize is an ideal forage crop for ensilage because of its high levels fermentable carbohydrates, although it low in protein. Sunn hemp a legume with crude protein content potential to be used combination maize provide silage higher content. Different percentages sunn hemp-maize mixtures 80-20, 60-40, 40-60 and 20-80 respectively were compared silages sole hemp. In the laboratory study, DLG clas...

The aims of the present study were to compare hydrodynamics of three pericardial and two porcine valves while performing at different stroke volume (SV) and increasing pulse rate (PR). Carpentier-Edwards Magna-21 (CEM), Sorin Soprano-20 (SS), Mitroflow-23 (MF), SJM-Biocor-Epic-Supra-21 (SJME), and Medtronic Mosaic Ultra-23 (MMU) were tested in the aortic chamber (23-mm in diameter) of the Sheff...

Abstract The Scuttle fly, Eurygaster integriceps Puton (Hemiptera: Scutelleridae) is a key pest of wheat and barley. univoltine migrates from fields following harvest to high elevations; then, the spring it moves back fields. Natural enemies may have an important role in decreasing population’s level overwintering sites. In present study, adults E. were collected sites Isfahan province, Iran, O...

A potential strategy for controlling pests is through the use of "companion plants" within a crop system. This strategy has been used in several trials to fight against a major crop insect pest: the aphid. We reviewed the literature to highlight the major mechanisms by which a companion plant may act. Trials carried out under laboratory or field conditions revealed that companion plants operate...

Crop rotation is a common means of reducing pathogen populations in soil. Several rotation crops have been shown to reduce soybean cyst nematode (Heterodera glycines) populations, but a comprehensive study of the optimal crops is needed. A greenhouse study was conducted to determine the effect of growth and decomposition of 46 crops on population density of H. glycines. Crops were sown in soil ...

The study was conducted among the two farmer groups in Bhaktapur and Kavre districts of Nepal. The main objective of the study is to evaluate the effectiveness of IPM FFS on creating awareness and disseminating the knowledge on sustainable pest management to the farmers and to assess the relationships between enhanced IPM knowledge and adoption of IPM strategies by the farmers. The study has be...
