Abstract

The study showed that the use of the magnetic field has positive effects on seed germination and plant growth of tomato , it has been shown that the best ratio of vitality and germination of seeds appeared when exposing the seeds for 8 minutes to a magnetic field strongly in 1800 chaos where it was tested several periods of exposure 0 , 2, 4 , 8 and 16 minutes reaching 83 , 100, 90 , 93, 100 , 93 and 83% , respectively, compared with the control treatment , which amounted to (80%) study also demonstrated the best combination of organic fertilizer in terms of quantity and quality , which included two types of compost and are remnants of rice and remnants of wheat where outperformed the treatment of manure waste 1:1 on all transactions where the total length and weight Bared 28.The conditions in the plastic house has achieved treatment F.o.l. + Salicylic acid + P. fluorescens for the dry weight of the root system and vegetative 0.16 g and g 0.5 , and the treatment of P.fluorescens amounted to 0.22 g and 0.3 g , respectively, amounted to treatment comparison 0.5 and 0.20 , respectively, as varied all transactions significantly compared to the treatment of F.o.l. ( plants inoculated with pathogen only) where achieved a 0.5 and 0.15 , respectively. The results of laboratory experiments reinforced the results of the experiments the plastic house and confirmed the effectiveness of different treatments , as it showed the treatment of yeast S.cereveciae highly efficient in encouraging recorded for the dry weight of the root system and vegetative 0.35 and 1.5 g have varied significantly for the treatment of ( F.o.l.) plants inoculated with pathogen only ( reaching 0.5 and 0.15 g . has also led transactions factors resistance vital in improving the rates of some indicators of output ( number of inflorescences per plant and the percentage of the contract and fruit weight and the amount of winning ) , as well as some signs of vegetative growth ( dry weight of shoots and roots and the number of forest / plant).

Abstract

This research was conducted to study the effectiveness of the fungusTrichoderma in reducing the severity of the disease and increase the growth ofsome growth standards tomato seedlings infected with fungi isolated from watersources for irrigation fields, Faculty of Agriculture. The results of isolation,diagnosis, there are 16 fungal genera, and the results show that the estimatedpathogenicity test using cabbage seeds In a growth chamber of tomato seedlingsthat All the isolated fungi from water sources at showed different percentagelevels of death treatment of Trichoderma sp showed to west death percent oncabbage seeds and tomato seedling before and after emergence at 14 , 20 , 4.2%respectively . Plastic house results showed that Trichoderma sp. Alone protecttomato seeds the death while Diplococcium and Rhizoctonia induced the highestdeath ratio before emergence at rate of 48.3 and 57.4% respectively while inafter emergence the Rhizoctonia treatment showed highest death ration 33.8 %.All treatment recorded reducing significantly the high of plant root size, rootweight, root dry weight and disease severity as compared with Trichoderma sptreatment which induced the plant characters at rate of 32.63 cm , 6.11cm3 ,0.459 gm. and 1.117 gm. respectively and reduced the disease severity .Treatment oh Trichoderma sp with all pathogenic fungi gave the beasttreatments in all vegetative characters compared with pathogenic fungi treatments .

Abstract

This research carried out in the laboratory of Technical Institute / Musayyibin 2011، has been tested six isolates local bacteria Bacillus thuringiensis on thefirst stage and the last of the larvae of a figs moth Ephestia cautela(Lepidoptera: Pyralidae) reared on the artificial diets ، while treated control withwater only. ، And took the percentage of mortality results after 2، 5، 8 dayssince results showed that the highest mortality rate of 96.6% on the eighth dayin each of the isolates DE 1-8 and NA 2-1 and DE 2-3 when Concentration 1.2× 106 spore /ml. While less kill ratio at treatment SL 4-1 in the concentration of1.2 × 104 spore /ml، amounting to 23.3%. isolation DE 2-3 achieved the highestrate at 72.2% at the concentration 1.2 × 106 spore /ml. within eight days، whilethe lowest rate was 23.3% when isolation SL 4 -1 Concentration 1.2 × 104spore /ml. The higher efficiency relative to Bacillus thuringiensis bacteria in themortality of the last instar larvae of the insect fig moth Ephestia cautella ratehas reached 34.7% in isolation DE 2-3 focus 1.2 × 106 after the fifth day، whileless relative efficiency rate was 6.8% when SL 4-1 in isolation Focus 1.2 × 104.The overlap between the concentration and the periods of isolation has achievedhigher mortality in DE 2-3 at 46.8% at the concentration of 1.2 × 106 spore /mlafter 5 days of treatment either at least it was 0.00% in isolation SL 4-1 at theconcentration of 1.2 × 104 spore /ml after 2 days of treatment. As for the larvaethat has not reached the stage of the pupae is observed that the lowest ratecould not be reached 52.6 when isolation DE 2-3 focus 1.2 × 106 spore /ml .Which differed significantly from the treatment comparison، while thepercentage larvae that could not is when isolation SL 4-1 in Focus 1.2 × 104 at94%، which did not differ significantly from the treatment comparison، eitheradult that emerged from these pupae There was no significant effect onemergence percentage compared to the treatment of comparison where thelowest percentage rise of 88.8% when isolation AN 8-3 consecration 1.2 × 106spore /ml while did not differ the rest of the other treatments for the of controlmortality. The mortality efficiency was shown in the last larval instarcompared to the first .

Abstract

The results of field study revealed that the density of two spooted red spi-der mites T. urticae in the observation periods had a significant differences, the highest maximum population densities were recorded within the periods of 1st and 3eal of March, the population were 31.2 Mite/Inch2, for both periods compared with other observed period. The analysis of Chemical pesticide ef-ficieus results showed that the pesticide Kumulus (after 72h of treatment ) had a significant effect in comparison with tested pesticides, which gave Mortalits percent of 57.74% in the adults of Mite flower, the experiment of Mites pathogens elucidated that both bioagents: Trichoderma harziianum and Beauveria bassiana had a positive effect in terms of biological contact of dust mites , their treatments led to a total mortality of 90% , for both patho-gen after 72 of treatment , compared with bacterial Suspension of Bacillus thurigienesis which led to a mortal its of 45.7% , The field experiment results showed that the chemical pesticide Ambactir decreased the population densi-ty of dust mites from 140 mites/inch2 to 36.7 mites/inch2after 14 day of treatment , without any differences from the pesticide Msulfur which de-creased the population from 80.4 mites/inch2 into 42.3 mites/inch2.

بينت نتائج الدراسة الحقلية ان كثافة اعداد الحلمة ذات البقعتين على نبات خيار القثاء اختلفت خلال مدة الفحص حيث بلغت الكثافة العددية اعلى مستوى لها في الاسبوع الاول والثالث من مايس عام 2013 ,اذ كانت 2 و31 فرد/انج2 لكلا الفترتين والتي اختلفت معنويا عن باقي مدة الفحص ( حزيران و تموز ) ,وفيما يخص تاثير المبيدات الكيميائية (Vertimec , M Sulfur , Kumulus ) لم تظهر النتائج اختلافات معنوية بعد 24 ساعة من المعاملة لكنها اظهرت فروقات عالية المعنوية بعد 72 ساعة من المعاملة اذ تفوق مبيد Kumulus على جميع المبيدات واعطى نسبة قتل 57.79 % في بالغات الحلمة ذات البقعتين، في حين اظهرت تجربة استخدام المسببات المرضية ضد الحلمة ذات البقعتين تأثيرا عاليا في القضاء على بالغات الافة بعد 72 ساعة من المعاملة اذ تفوق كلا الفطرين Beauveria.bassiana , Trichoderma harazianum في احداث نسبة قتل بلغت 90% لكليهما على التوالي واختلافا معنويا عن تأثير المعلق البكتيري لبكتريا Bacillus thuringiensis والتي اعطت نسبة قتل بلغت 45.7% ولنفس الفترة الزمنية ، اظهرت نتائج الدراسة الحقلية للمبيدات الكيميائية بعد (14) يوما من المكافحة تفوق مبيد vertimec في خفض اعداد الحلم من 140 فرد/ انج 2 الى 36.7 فرد/ انج2 والذي لم يفرق معنويا عن مبيد M Sulfur والذي خفض اعداد الحلم من 80.4 فرد/انج2 الى 42.3 فرد/انج2 .
