Effectiveness of different fungicides formulations and certain ground spraying equipment in controlling wheat stripe rust in Egypt

الملخص EN

Wheat (Triticum aestivum L.) is of the most important cereal crop for many world’s populations.

It is the most important staple food of about two billion people.

However, the production and productivity of wheat is affected by various biotic and abiotic stresses.

Among the biotic stresses, stripe rust caused by Puccinia striiformis f.

sp.

tritici (Pst), is one of the most widespread and damaging diseases of wheat.

Field experiments were carried out in an area of about three kirats planted with the susceptible variety (Giza160), during seasons 2017/2018 and 2018/2019 in 15th and 30th March in wheat field located at Sakha, Kafrelshiekh Governorate.

The selected area was split into 30 plots including 3 control plot.

Propiconazole, azoxystrobin + cyproconazole and cyproconazole + propiconazole were sprayed with the rate of recommended dose rate and three treatments sprayed with water as control by using Hydrulic Matabi evolution sprayer (56 L./fed.), Knapsack motor sprayer (Arimitsu) (43 L./Fed.) and Rotary Matabi sprayer (18 L./fed.).

Data indicated that, all tested compounds revealed significant influenced on wheat stripe rust pathogen (Pst).

Data of two successive sprays gave the same results since propiconazole occupied the first rank in reducing rust severity.

The best fungicide in this respect were propiconazole followed by cyproconazole + propiconazole, however azoxystrobint + cyproconazole was the least in this regard.

It could be recommended to use these compounds with LV spraying equipment with not less than (18L/Fed.).

Also, the best equipment in this respect were Rotary (Matabi) followed by Hydraulic (Matabi) and Knapsack motor sprayer (Arimitsu) the tested equipment under study.

Hence, the yield production was high in the best fungicide and equipment.

The rate of performance of Arimitsu sprayer was 15.25 Fed./day, but the lowest rate of performance was Rotary Matabi sprayer since it could spray only 2.3 Fed./day.
