Opinions on the Occurrence of Sclerotinia Rot in Rapeseed and Its Control Techniques
This year's rapeseed growth is characterized by an earlier growth period than last year and a growth vigor close to last year's. The occurrence characteristics of rapeseed sclerotinia rot this year differ from previous years. Based on a comprehensive analysis of multiple factors including field inoculum sources, rapeseed growth vigor, varietal disease resistance and climatic conditions during the susceptible growth period, the natural occurrence level is a moderate-to-severe epidemic. ...

What does "flowers but no seeds" mean in rapeseed cultivation?
What is rapeseed "flowers but no seeds"? What methods are there to prevent and control it? Please explain. Rapeseed "flowers but no seeds", also called stunted sterility, means that from the onset of the disease to maturity, the plant keeps flowering continuously but cannot set seed normally. The main cause is a physiological disease caused by growing rapeseed on boron-deficient soil, mainly occurring in Brassica napus varieties, but in recent years it has also been found in Brassica rapa rapeseed. After the disease occurs, yields generally drop by 20% to 30%, and in severe cases there is even almost no harvest, making it a problem worth attention in rapeseed production.

Detailed explanation of the double-low rapeseed minimal and no-tillage relay direct seeding cultivation technique
Controlling rapeseed powdery mildew well is a prerequisite for obtaining high yield and high quality in rapeseed, while autumn-sown rapeseed at the final flowering stage and the middle-to-late pod stage is precisely in the March-April period of high temperatures and shading between plants, when powdery mildew occurs rather commonly, greatly reducing the 1000-grain weight of rapeseed and thereby affecting yield; therefore, the control of rapeseed powdery mildew is very important. 1. Harm...
