The effects of calcium propionate, sodium bicarbonate, and sodium ethylenediamine-tetraacetic acid (EDTA) on postharvest pathogens of apple and peach, and on improving the efficacy of the biocontrol product Aspire were evaluated. All three materials had a distinct inhibitory effect on the radial growth of Botrytis cinerea and Penicillium expansum in vitro. The inhibitory effect increased with t...

The Pacific islands have a diverse range of food and cash crops with indigenous and introduced nematode problems. The staple food crops have serious nematode pests, such as Meloidogyne spp. on sweet potato, Hirschmanniella miticausa causing corm rot of taro, and Pratylenchus coffeae and Radopholus sp. producing tuber dry rot of yams. Bananas are infested with P. coffeae or R. similis, citrus wi...

Diseases are still the main cause of reduction of yield in tomato crops in Pakistan. Early blight and fruit rot of tomatoes are the most important diseases caused by Alternariasolani. These diseases are responsible to cause tremendous yield loss in tomato crops in District Mansehra, Khyber Pakhtunkhwa, Pakistan. This research was initiated to isolate the causal agents of early blight and fruit ...

Various farm wastes were investigated as substrates for Pleurotus tuber-regium. The highest mushroom harvest (fresh weight) was obtained from oil palm fruit fiber substrate and the lowest yield was from yam (Dioscorea sp.) peelings. Casing enhanced yield from all substrates. Oil palm fruit fiber spawn is an alternative to the sclerotium in propagating the fungus. Some fungi and pests were assoc...

Tomato (Solanum lycopersicum L.) fruit is an important component of the diet but pathogens are a threat to its availability. The purpose this research work was identify fungi associated with tomato rot and study their biomass in different carbon nitrogen sources. Four varieties were employed study: two local (Hausa Yoruba land races) improved (Tropimech Roma VF). Freshly harvested fruits collec...

Abstract Background The release of pollutant gases into the atmosphere as a result anthropogenic activities exert effect on biological systems at many levels. Combustion engines such those in vehicles and power generators pollute air with emissions from their exhausts. released which are oxides carbon, nitrogen; sulphur particulate matter have living things immediate environment. Up to 25% harv...

Species in the genus Gliocephalotrichum (= Leuconectria) (Hypocreales, Nectriaceae) are soilborne fungi, associated with post-harvest fruit spoilage of several important tropical fruit crops. Contemporary taxonomic studies of these fungi have relied on morphology and DNA sequence comparisons of the internal transcribed spacer region of the nuclear rDNA (ITS) and the β-tubulin gene regions. Empl...

Blueberries (Vaccinium corymbosum, cvs. Collins, Bluecrop) were exposed to ultraviolet light-C (UV-C) radiation treatments from 0 to 4 kJ/m2 rior to 7 days storage at 5 ◦C plus 2 days at 20 ◦C, 90% RH. Weight loss and firmness were not affected by light treatment. Decay incidence from ipe rot (Colletotrichum acutatum, syn. C. gloeosporioides) on fruit was decreased by 10% with 1–4 kJ/m2 UV-C li...
