These resistance inducers were tested at three concentrations 100, 200 and 300 μM for SA, IAA, and Eth and 15, 20 and 25 μM for JA while the biofertilizer was tested at 7g/L as biotic resistance inducers against root-knot nematode Meloidogyne incognita under greenhouse conditions at the Faculty of Agriculture Shebin El-Kom, Menoufia University in season 2016. All concentrations of the tested inducers significantly reduced root-galling and nematode population in soil as well as the number of egg masses and developmental stages per root system. The greatest inhibition effect on reproduction of nematode was recorded with Eth at 300μM, which did not significantly differ from that of a nematicide-treated plants. Also, all treatments significantly enhanced all vegetative plant growth characters compared with the infected plants. Biochemical analysis showed a significant increase in the activity of antioxidant enzymes (peroxidase, polyphenoloxidase and catalase), total and reducing sugars, and total phenols at the highest concentration of the tested inducers, especially, Eth compared with the nematode-infested plants. Histological studies indicated that less giant cells were observed in almost all treatments compared to the nematode-infected control plants. However, the highest concentrations of IAA, Eth (300μM) and Halex-2 treatments showed a good performance, with no giant cells found. Sixty days after nematode inoculation, all treatments (except SA and Halex-2) showed a poor formation of regular giant cells divided from cytoplasm and contained less number of nuclei compared to the infected plants. It seems that the tested inducers could be recommended to control M. incognita on pepper plants. Thereby, decreases the costs and side effects of using nematicides.","PeriodicalId":168502,"journal":{"name":"Egyptian Journal of Crop Protection","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114118480","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}

Greenhouse results showed that T. hamatum (1, 2) showed the highest percentage of survival plants infected with M. phaseolina isolates (1 and 3) while the lowest percentage of survival plants obtained with T. harzianum.

Two magnetic levels were used to produce a high magnetic field, (MF1) = (20.8 mt. in lower and 1.3 mt. in center jars) and another low, (MF2 = (2.1 mt in lower and 1.21mt in center) compared with non exposed adults (control). The results demonstrated that the total eggs laid /female and hatchability in exposed adults were highly significantly affected compared with control. Mean numbers of eggs laid/female were 77.0 and 109.6, when adults were exposed to MF1 and MF2, respectively, compared with 175.0 eggs/ female in control. The percentages of eggs hatchability were 49.6 and 79%, in exposed adults to MF1 and MF2 respectively, compared with 95 % in control. Data reported that exposure of adults to selected magnetic fields; MF1 and MF2 reduced the mean number of eggs /female. Percentages were 56% and 48.8% when exposed to high and low power (MF1and MF2) respectively. The results indicated that longevity of exposed females and males were significantly affected compared with control. Longevity of adult males decreased to about half the time when exposed to high powers MF1, the longevity of exposed males to MF1 and MF2 were 6.6 and 9.6 days/ male, respectively but it was 13.3 days/male in control. In females, the longevity decreased after exposure to the higher MF, whereas prorogated after exposure to the lower magnetic levels, the longevities of exposed females to MF1 and MF2 were 12.8 and 16.4 days / female respectively, compared with 15.8 days / female in control. In additions, the effects of exposure to the magnetic fields MF1 and MF2 on some biochemical parameters were determined.
