Which fungicides are effective for controlling Fusarium wilt in cowpeas (Vigna unguiculata)?
In the early stage of the disease, you can use a 1000-fold dilution of 50% carbendazim wettable powder, or a 400-fold dilution of 10% Shuangxiaoling aqueous solution, or a 1000-fold dilution of 75% thiophanate-methyl wettable powder, applying 50 to 150 grams per plant, once every 7 to 10 days, for 2 to 3 consecutive applications. Alternatively, mix 500 grams of 50% carbendazim wettable powder with 200 kg of dry soil and apply it in furrows along the sowing rows at 200 kg per mu.
