orange/citrus splitting disease
Posted: 14 Jun 2015, 16:23
Hi sir,
i need some advice about my poor orange tree! orange drop suddenly by splitting after heavy rains.before the rain there is extreme summer days temp about 45 degree to 46 degree
also about fruit scab distorted as seen in image(orange split 005)
The rind splits when water and sugars are transported from the roots of the tree to the
ripening fruit and rind is unable to expand quickly enough to accommodate the added
volume (Fig. 1-7)
• Splitting seems to be caused by a combination of factors including extreme fluctuations
in temperature, humidity, soil moisture and fertilizer levels
• Splitting varies seasonally and is usually greatest where crop load is heavy
• Split usually starts at the blossom end of the fruit (which is the weakest point in the rind)
• Split can be short and shallow or deep and wide, exposing the segments of the juice
vesicles (Fig. 1,2-4)
• Fruit on young trees are more prone to fruit splitting than fruit on older trees
• Splitting wastes the fruit, and creates a good breeding ground for fruit flies, so the split
fruit should be removed and treated
