Dew condensation on the leaf surface of greenhouse crops can promote diseases caused by fungus and bacteria, affecting the growth of the crops. In this paper, we present a WSN (Wireless Sensor Network)-based automatic monitoring system to prevent dew condensation in a greenhouse environment. The system is composed of sensor nodes for collecting data, base nodes for processing collected data, re...

Anthracnose of papaya fruit caused by the fungus Colletotrichum gloeosporioides is one of the most economically important postharvest diseases. Hot water immersion (HW) and calcium chloride (Ca) treatments have been used to control papaya postharvest diseases; however, the effect of the combination HW-Ca on the pathogen growth and the development of the disease in infected papaya fruit has been...

Abstract The study was carried out in the Forest Diseases Laboratory, Department of Sciences, College Agriculture and Forestry, University Al Mosul. During academic year 2021-2022, Sakla wood is available stores city aimed at effect decay fungi on some local commercial woods, including populus Eucalyptus results field survey Mosul showed that most infected with brown rot fungus. As severity inf...

None (Members of Erysiphales cause powdery mildew diseases on wide host rang and produce whitish primary mycelium on surface of infected parts. Based on microscopic study of one specimen on Jasminum sp., structures of fungus including conidiophores and conidia were observed. Foot cells of conidiophores were cylindrical or curved in basal part, followed by 1-2 shorter cells. Conidia were ellipso...

The effects of 22 pesticides on the mycelial growth and pathogenicity of the biocontrol fungus ARFI8 to Heterodera glycines were tested in vitro. The chemicals were added to agar at 10, 100, and 1,000 ppm a.i.; a block of agar containing the fungus was added to each test concentration; and fungal growth was measured. Subsequently, a block of the fungus on the pesticide-containing agar was used ...

Beauveria bassiana (Balsamo) Vuillemin was tested under maximum challenge conditions with an estimated dose of 1.1 × 10 5 conidia/mm 2 for its effects on eggs of four of the major beetle pests of stored grain and grain products. When ambient relative humidity (RH) was 92%, hatch of fungus-treated Rhyzopertha dominica (Fabricius) eggs was 13% versus 58% for control eggs, and hatch of treated Tri...

The fungus Clonostachys rosea was recognized as an aggressive parasite on other fungi already in the late 1950s. Research into its potential use biological control of plant diseases soon followed. Today, there are several commercial products based C. available for biocontrol applications worldwide. Although mycoparasitic ability has attracted a lot interest, is now viewed ecological generalist ...

The postharvest life of mango is limited by the development of pathogens, especially fungi that cause rot, among which stands out the Lasiodiplodia theobromae. Several control methods have been employed to minimize the damages caused by this fungus, chemical control can leave residues to man and nature; physical control by the use of gamma radiation in combination with modified atmosphere and c...

Chemical insecticides play an important role in the control of plant damage and plant diseases. However, extensive use of these products has led to the disruption of ecosystems because of several reasons such as death of non-target species, accumulation of pesticide residues in the environment and food, and buildup of pesticide resistance in the target species. Biological control is one of the ...
