Control methods of Sclerotinia sclerotiorum in sunflower
In order to control Sclerotinia sclerotiorum, we should first pay attention to the implementation of crop rotation and removal of disease residues. Promote the rotation of sunflowers with millet, millet, corn and other gramineous crops, and avoid continuous cropping with legumes and eggplants. The number of years of rotation is at least 3-5 years. Remove the straw as far as possible during the autumn harvest, dig out the stubble and turn it more than 10 cm deep. The second is.

New ways to manage rape in winter
Generally speaking, the boron content of cruciferous crops is higher than that of monocotyledon crops, and the crops with high boron content usually have a high demand for boron. Boron can promote the normal development of reproductive organs of boron-loving crops such as rape, accelerate pollen germination and pollen tube elongation, which is beneficial to fertilization and fruiting. When boron deficiency occurs, these organs are likely to wilt.
