SUBREGION I

BACKGROUND FOR THE CROP

        

It was a wet end of the 2017 wheat crop season, with moderate temperatures..

Only three frosts were recorded in June and July. Frost damaged the crop that was still booting.

Rainfall in August and September was 115 mm, very favorable for bacterial and fungal diseases, especially, stem fusarium (Fusarium graminearum.) Yield loss due to stem fusarium is estimated to be over 40%. Crop looked good until flowering. Fusarium was present in all varieties; however, the proportion of stems affected was different.

Some blight, bacterial infection and yellow spot symptoms were observed before flowering (Drechslera tritici repentis). At grain filling, leaf rust (Puccinia triticina) and stem rust (Puccinia graminis) affected the crop.

Grain protein content was between 9 and 12%. Test weight was low or very low, and the number of grains per square meter was between 21 and 35g.​
