Are you still online? No, the quality of your cowpea is not very good. Oh, it's white. The cowpea at the back of the picture has a pointed tail. If it's not the variety, it's the fertilizer or pesticide. Try to remember not to water the pods when they are too dry, nor to apply nitrogen fertilizer unilaterally, nor to beat hormones indiscriminately. Now apply some balanced fertilizer and put some amino acid foliar fertilizer+brassin on the leaves to adjust and relieve. Moreover, there are a little irregular white spots on the leaves in the picture, which are caused by the harm of liriomyza sativae. On the basis of amino acid foliar fertilizer and brassin, abamectin or mirex can be sprayed at the same time.
