Developing alternative control methods such as using beneficial microorganisms and their metabolites to control the plant diseases has gained so much importance along recent years and research on this area are increasing day by day. In this study the possibilities of using microorganisms which have antimicrobial effects on controlling soil-borne fungi at strawberry production were investigated. Effects of different lactic acid bacteria (LAB) strains were studied in vitro and in vivo against the development of several soil-borne fungi. LAB were screened for antifungal activity by using cell free supernatant against Fusarium sp., Rhizoctonia sp., Macrophomina sp., Botrytis sp., Phtopythium sp., Cylindrocarpon sp. and Pestalotiopsis sp. Cell free supernatant of LAB isolates showed antifungal activity against fungi. In vitro effective strains of LAB were used in pot experiments to search their effects on fungal development and the development of the plant. While the antifungal effects of all LAB strains tested in vitro experiments exhibited promising results, in vivo experiments revealed similar effects on different fungi genera.

Anatolia has a wide range of variety and species of grape due to its location is within the native lands of the grape. Turkey is one of the world’s major winegrowing centre because it has an important potential in terms of vineyards area and grape production. Today, people have turned to organic farming due to unbalanced population movements, depletion of natural resources, climate change, conscious consumption and food security. Organic agriculture is an agricultural system that aims to evaluate the future of human and ecosystem as an indivisible whole with healthy plant and animal production. Grape is in the first place in terms of trade among horticultural plants worldwide. In this context, grape is one of the most important of the 197 organic crops grown in our country. The large proportion of organic grapes produced in our country is dried and the organic dried grape is exported abroad. Therefore, the demands of the foreign market are great importance. With this research, the recent situation of organic viticulture in our country has been reviewed and suggestions have been made for improvements.

Unio tigridis has an importance for the biodiversity of freshwater ecosystem of the Turkey. However, there is no available literature in the world on the growth of this species yet. The aim of this study, therefore, was to describe the age, growth and mortality of this species living in Lake Gölbaşı from Hatay providence, Turkey. A total 428 of specimen were collected using by divers with hand dredges in depth of 1 to 6 meters based on annual sampling strategy from June- 2004 to May- 2005. Lengths and weighs of sample were ranged as 2.1 to 9.2 cm (6.79 ± 1.52) and 1.1 to 73.05 g (34.18 ± 15.56), respectively. Weight-Length relationship of all specimens was described as W=0.193L2.63 (R2=0.94). Thus, a negative allometric growth was detected in the sampled population. The age of each individual was determined by counting the external shall annuli-growth interruption lines. The sampled population was composed of 18 age classes. Specimen belong to age class 7 was the most presented with 20.33 percent in the population. The rate of male to female (m:f) was 0.91:1. Seasonalized von Bertalanffy growth model (SVBGM) was used to describe the growth. From these results, it was shown that seasonality in growth does not occur in this lake for this species (L∞ = 8.80 cm (Shell Length), K = 0.271 year-1, t0 = -0.161 year, C = 0.014, ts = 0.100 year with RSS = 23.22). The total mortality rate (Z ± Se) was calculated as 0.401 ± 0.015 year-1 with R-square = 0.99 (CL of Z with 95 % = 0.361 - 0.440 year-1). Although, there is no fishing, no pollution and no predation risk on this species yet, due to growth characteristic, high K and low L∞, this type of species are vulnerable to extinction.

Cypermethrin is a large spectrum action insecticide, globally employed to control pests in agriculture and some human and domestic animals ectoparasites. This study aimed to evaluate its toxicity and reproduction impairment in male guinea pig. Forty adult male guinea pigs were divided into 4 groups and orally submitted to 0, 92, 137.5 and 275 mg/kg body weight/day for 90 days. The weight of the liver increased significantly, while that of kidneys decreased significantly in treated animals compared to controls. Serum concentrations of creatinine, urea, ALAT, ASAT, total cholesterol, prostatic acid phosphatase increased significantly, while the testicular total protein level decreased significantly in groups given the insecticide relatively to the control. The testes weight, libido, serum level of testosterone, mobility, sperm count and the percentage of spermatozoa with entire plasma membrane decreased significantly in animals exposed to cypermethrin with reference to controls. The percentages of abnormal spermatozoa increased significantly in animals submitted to 137.5 or 275 mg/kg body weight (bw) of cypermethrin compared to control ones. On the testis histological sections of pesticide-treated animals, immature germinal cells were observed in the lumen of seminiferous tubules. Cypermethrin was toxic in male guinea pig and damaged reproductive parameters.
