لدراسة تأثير بعض المبيدات الفطرية مخبرياً على عزلة من الفطر (Cladosporium fulvum (cooke ، المسبب لمرض العفن الزيتوني على البندورة ، تم اختبار خمسة مبيدات فطرية Flint- Topsin-M- Score- Collis- Indofil-M ، بتركيزات تراوحت بين 1 و 4000 جزء في المليون. تبين أن المبيدين Score و Indofil-M من أكثر المبيدات تأثيرا ً في منع نمو الخيوط الفطرية للعزلة ، حتى بالتركيز 10 جزء في المليون, كما منعا إنتاش الأبواغ بصورة كاملة بالتركيز 100 جزء في المليون. كان تأثير المبيدين Flint و Collis ضعيفاً في منع نمو الخيوط الفطرية للعزلة ، في حين منعا إنتاش الأبواغ بصورة شبه كاملة بالتركيز 1000 جزء في المليون. لم يلاحظ تأثير واضح للمبيد Topsin-M في منع نمو الخيوط الفطرية ، في حين منع إنتاش الأبواغ بالتركيز 1000 جزء في المليون.
To study the effect of some fungicides invitro on an isolate of the fungus Cladosporium fulvum(cook) that causes leaf mold on tomatoes, five fungicides were tested Flint - Topsin-M- Score and Collisand Indofil-M at concentrations between 1 - 4000 ppm. The results showed that Score and Indofil-M were the most effective fungicides inhibiting hyphal growth for the isolate even at 10ppm. Also, they inhibited completely the spores germinatios at the 100 ppm. The effects of fungicides Flint and Collis were weak on hyphal growth of the isolate and inhibited almost completely the spores germinatios at 1000 ppm. We didn,t observe clear inhibiting effects of Topsin-M on hyphal on the growth of the spores germinatios at 1000 ppm .

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.
To know the effect of some fungicides on peacock eye disease has beentested five
fungicides from different chemical groups, using concentrations advisable to field
application,on the 45 year old olive trees in the Baksa village Lattakia . The resul
ts
showed an increase in incidence of the control of 22.4 to 45.5 % after 45 days, versus low
incidence rates in the fungicides tested treatments . The best two fungicides were
thiophanate –methyl with infection decreasing from 19.2 to 10.3% and chlorothalonil from
24.3% to 16.5% . The severity also decreased in the treatment of the fungicide thiophanate
–methyl from 9.7 to 4.1 % and chlorothalonil from 13.7 to 8.9 % while the severity of the
infection of the control increased from 10.5 to 25.6 % .In order to efficiency the fungicide
thiophanate – methyl was more effective reducing the infection severity compared with the
control with 82.8 %, followed by chlorothalonil , kresoxsim methyl , and mancozeb with
73.3 , 72.0 , 71.9% respectively whereas the fungicide copper oxychloride was the least
effective with 68.1%.
Ascochyta blight, which is caused by the fungus Ascochyta fabae f. Sp. Lentis, is
considered as a very important fungal disease that infects lentils and cause it damage.
The experiment was conducted in ICARDA research station for agricultural exper
iments in
the orchard area Basha, Jableh, Lattakia in four varieties of lentils that are grown in
different parts of Syria, and these varieties are: Idleb 2, Idleb 3, Idleb 4, and municipal red.
Artificial infection was performed using a local isolation of the fungus Ascochyta lentis
with an average of three times and ten days between each infection and the other. The
infectious vaccine adopted a concentration of 105 Båge / ml.
A Study was carried out to evaluate the impact of some insecticide.
The results showed that no effects on growth of the studied fungi
were observation when Deltamethrin and Chlorpyrifos were used by
the low concentration.
