The effect of some essential oils taken from Cinnamomum zeylanicum, Citrus limonum and Rosmarinus Officinalis was investigated in relation to the growth of bacteria Paenibacillus larvae which causes American Foulbrood disease that affects world honey bees Apis mellifera L. The study was carried out in the laboratories of the Faculty of Agriculture, Damascus University from 2012 till 2013. This is in order to contribute to preparing an integrated pest management program for American Foulbrood disease. The oils were extracted from the plants using steam distillation. The effects of the concentrations of oils on the growth of P. larvae were tested between (3.90625 - 500 μg/ml) using agar disc diffusion in petri plates. Results showed that the essential oils used stop the growth of P. larvae in some of their concentrations. The minimal inhibitory concentrations which stop the growth of P. larvae of the oils of Cinnamomum zeylanicum, Citrus limonum and Rosmarinus officinalis were recorded at 31.25 μg/ml, 62.5 μg/ml, 125 μg/ml respectively.

Symptoms of soft rot showed in some fields cultivated with garlic crop in the Kissweh region (Damascus countryside). Studying this disease, found that the incidence rates ranging between 2.91% to 5.59%. 55 bacterial isolates were isolated from inf ected samples collected during the seasons 2005 and 2006. The results of five biochemical tests showed that 22 isolates were pectinolitic and they were pathogenic to garlic plant and gave symptoms similar to those observed in the field, theses isolates were classified as belonging to the genus Pectobacterium. To determine the species of the bacteria, they have been characterized towards nine biochemical tests, which allowed the classification of 7 isolates as Pectobacterium carotovorum subsp. carotovorum, 6 isolates belonged to Pectobacterium atrosepticum, one isolate to Dickeya chrysanthemi (Pectobacterium chrysanthemi), 6 isolates have not been classified and 2 isolate did not characterized . These results have shown for the first time the isolation and identification of the Pectobacterium bacteria causing soft rot on garlic crop in Syria.
Field experiment was carried out at Research Station of the Faculty of Agriculture, Muthanna University, Iraq, during 2014/2015 season, to study the effect of adding NPK, biofertilizers Bacillus Subtilis and Glomus Mosseae on the growth and yield of maize (Zea may L.). The treatments were i.e control (zero: no vaccine), biofertilizers Bacillus subtilis treatments, Glomus mosseae, both biofertilizers (F0, F1, F2 and F3), respectively, Three levels of NPK liquid fertilizer i.e. 0, 5000, 7500 mg )C0, C1, and C2 respectively). The experiment design was RCBD with three replications arranged according to split plot.
Samples of Trout dived into aqueous extract of ginger in different concentrations (5-15-25)% for one minute and then preserved at 4±1 cº for 13 days. It has studied the effect of aqueous extract of ginger in bacterial load, including general bacterial census and the census of pseudomonas. It was also identified the values of the pH and some organoleptic qualities of meat such as color, smell, texture and taste.
Effect of different degrees of temperature, different levels of pH , different periods of light and four media (PDA, OMA, MEA, CzA) was studied in vitro against the growth of C. gloeosporioides causing anthracnose disease of citrus fruits. The resu lts indicated that the growth of fungus was maximum at temperature 30°C and at pH = (5.5,6,6.5), and Light was unnecessary for the growth of C. gloeosporioides. Among the different media tested PDA and OMA supported the maximum growth of fungus.
The research was conducted to study an efficacy of the fungus Trichoderma harzianumin controlling the gray mold disease on tomato that causing by the fungus Botrytis cinerea. A local isolate of the fungus T. harzianum was studied under laboratory conditions using two methods: antagonism and the spore suspension.
