The flat mite, Tenuipalpus eriophyoides Baker was recorded for the first time in Egypt, whereas female and male were re-description. This mite species infesting date palm trees on the underside of leaflets in moderate numbers causing, extensive yellowing of lower leaves may be symptomatic of either –flat palm mite T. eriophyoides feeding or any of several pests or disease of palms. In this respect, biological and ecological studies were carried out to know different developmental stages and fecundity when reared on date palm leaflets Zaghloul variety under laboratory conditions. Seasonal abundance of the flat mite, T. eriophyoides infesting date palm Zaghloul and Sewi varieties in Sohag Governorate, along two seasons 2015 and 2016. Obtained data cleared that the T. eriophyoides passed through egg, larva and two nymphal stages before reaching adult. The average length of the egg stage is (13.5 & 11.2) and (11.2& 10.8 days) for female and male at 20°C and 30°C when mite reared on Zaghloul variety leaflets. 15.72 to 22.5 eggs were laid in 18.5 and 15.0 days with a daily rate of 0.85 and 1.5 eggs in the same trend. The life span lasted (63.1 & 43.7) and (44.9 & 34.3 days) for female and male, when they fed on leaflets of date palm, Zaghloul variety at 20°C and 30°C. The occurrence and seasonal abundance of the flat spider mite T. eriophyoides infesting data palm trees, zaghloul and Sewi varieties was investigated during the period from May to mid Nov. in 2015 and 2016. The population started in few numbers in May, then increased to its, peak in August on both varieties, also, data showed that Sewi variety had the higher infestation than zaghloul variety. In general season 2016 was high level infestation than season 2015, due to climatic factors.","PeriodicalId":332125,"journal":{"name":"Menoufia Journal of Plant Protection","volume":"145 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120872794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is an exclusively seedborne disease and can be controlled by applying pre-sowing dry seed treatment with any of the nature products as black seed oil and cumin oil or gamma rays@ 150, 200, 250 Gy or four systemic fungicides as Premis® 25% FS, Sumi-8® 2%WP, Dividend Extreme® 11.5% FS and Raxil® 2% DS. The present study was carried out during 2016/2017 and 2017/2018 growing seasons and aimed to evolve an efficient method of application of fungicides, nature products and radiation for an economic control of loose smut of wheat and also evaluated for the determination of four azole fungicides residues in wheat and soil samples. The tested fungicides were highly effective in controlling the disease and gave more than 98% disease control with high grain yield while nature products as black seed oil and cumin oil gave 61.2% and 56.6% control, respectively. For determining the fungicides residues, the fungicides were extracted and cleaned using the ‘Quick Easy Cheap Effective Rugged and Safe’ (QuEChERS) method and followed by gas chromatographs coupled to electron capture (μECD) detector analysis. The analytical method was evaluated in terms of recoveries, repeatability, limit of quantitation (LOQ) and matrix effects. The recoveries were between 80.12 to 97.85% with relative standard deviation (RSDs) ranged between 6.12-10.65%. Limit of detections ranged from 0.002 to 0.01mg/kg.

Wint., is the most serious fungal disease affecting apple trees in many apple production areas of the world and Egypt, that resulting in the defoliation of trees and making the fruits unmarketable. Depending on the risk of disease, 8 to 10 or even more fungicidal applications usually need for efficient control. If the disease is not controlled at the suitable time of application, the disease can affect 70 % or more of the yield. Field studies were conducted during 2017 and 2018 growing seasons in two districts of two Governorates of Egypt, i.e. Qalyoubia at El-Qanater El-Khayria Horticultural Research Station, Agricultural Research Center, and Beheira at a private farm at Kafr El Dawar. The efficiency of different tested fungicides and the time of their application (four variable times) on controlling the disease and fruit yield production were estimated. Time of application have markedly affected the efficiency of the fungicides that used. Disease suppression and fruit yield (kg/tree) were greater when the tested fungicides were applied at the third application program (at fruit set in the first week of April when the first symptoms of scab infection were observed), followed by the second application program (at full bloom in the first week of March), while fungicide applications at the first application program (at bud burst in the first week of February) and the fourth application program (at fruit growth in the first week of May) recorded the highest disease severity% and the lowest yield productivity (kg/tree) in the two governorates through the two growing seasons. Bellis, Amistar top and Score had more effect on apple scab infections and yield productivity (kg/tree), followed by Occidor, Topsin M and Namrod but the lowest efficiency% and the lowest productivity of yield (kg/tree) were recorded with Dithane M, Index, Copper oxychloride and Microvit through 2017 and 2018 growing seasons in the two governorates.

The spider mite, Tetranychus urticae Koch considered one of the main pests, which threatens the soybean crop yield. Three field experiments were conducted during the season, 2017 at Kafriklaa, El-Santta district, Gharbia Governorate, to evaluate some environmentally safe materials; some plant extracts and the efficiency of the predatory mite, Phytoseiulus persimilis (A.-H.) in controlling the two spotted spider mite, T. urticae infesting soybean. Obtained results showed that mixture of Vertimec + Super-Misrona oil exhibited the highest reduction (94.4%) followed by Vertimec + Micro-elements (92.2%), Vertimec alone (88.55%), Super-Misrona oil + Micro-elements (78.2%), Super-Misrona alone (75.4%) and Liquid-Sulphur (70.8%). The efficacy of the three plant extracts could be arranged in a descending order as follows: 68.7, 62.7 and 57.2% for Oshar (Calotropis procera Ait), Black shadenight (Solanium nigrium L.) Unrip- fruit and Neem (Azadirachta indica A. Juss) extracts. The third trail was releasing the predatory mite, P. persimilis with rate of 15-20 mites/hill during seedling stage of soybean plants and the level infestation 3-5 mites/plant. The population of spider mites reduces 71.5% after 8 weeks of releasing and the level of infestation had become under threshold for the end of season.","PeriodicalId":332125,"journal":{"name":"Menoufia Journal of Plant Protection","volume":"1098 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116046006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eight fungal isolates were isolated from diseased plants representing different localities in different governorates i.e. El-Kassasen (Ismailia Gov.), Kafer El-zayat (Gharbia Gov.), El-Katatba (Minofya Gov.), Housh-Essa (Behera Gov.), El-Badrashen (Giza Gov.), Behdal (Minia Gov.), Dairoot (Assiut Gov.) and Shandaweel (Sohag Gov.). The obtained isolates differed in their culture color, number and size of sclerotia. Isolates which isolated from El-Kassasen, Kafer El-zayat, El-Khatatba, El-Badrashen and Behdal, were belonging to AG-3 anastomosis group. Under greenhouse conditions this isolates were tested for their pathogenicity to potato (Lady-Roseta cv.), during summer growing season 2015 and gave high rates of infection to potato plants. In this manner, the isolate which obtained from El-Badrashen (Giza Gov) was the highest aggressive one and causing the highest percentage of stem canker and black scurf. In separate experiments under greenhouse conditions, a number of biocontrol organisms, animal manure extracts and fungicides were evaluated alone in their efficacy to reduce the infection of potato stem canker and black scurf diseases.With regard to bioagents test, Trichoderma harzianum at concentrate 2.0% improving percentages of eyes germination and reduce dead sprouts of potato and decrease of stem canker and black scurf incidence, compared with Bacillus subtilis and algae treatments. While, animal manure test, Pigeons extract at concentrate 2.0%, gave the highest effect on reducing of stem canker and black scurf incidence compared to Chicken extract. In fungicides experiment, Rizolex (Tolchlophos-methyl) when used before soil inoculation give the best effect in reducing of non-germinated eye, dead sprouts and incidence of stem canker and black scurf compared to Monceren (Pencycuron). On the other hand, the effect of different treatments on the content of potato plants of phenols and oxidative enzymes were studied.
