Currently, spring rice is in the stage of panicle initiation and flowering. Farmers need to proactively prevent and control small leaf rollers in high density areas with specific pesticides such as: Incipio 200SC, Director 70EC, Dylan 5WG, Comda Gold 5WG... Spraying time is when larvae are 1st - 2nd instar. Small brown planthoppers, white-backed planthoppers appear in the stage of panicle initiation and flowering with high density (mostly white planthoppers) need to be prevented with systemic pesticides such as: Chess 50WG, Chatot 600WG, Afta 300WP... Proactively spray to prevent neck blast disease on areas infected with leaf blast disease, especially on susceptible rice varieties such as glutinous rice, Q5, Thien Uu 8..., especially when rice is in the flowering stage and there is rain and high humidity. Spray prevention with one of the specific drugs such as Bankan 600WP, Dojione 40EC, Filia 525SE, Bump Gold 40SE, Angate 75WP..., spray when the rice has ripened 3-5% of the area. For rice ripening after May 10, if the weather is hot and the air humidity is low, there is no need to spray prevention. Sheath blight disease occurs and causes damage, it needs to be prevented with specific drugs such as Tilt super 300EC, Sagograin 300EC, Nevo 330EC, Anvil 5SC... Bacterial leaf blight - streak disease appears, it needs to be proactively prevented early with drugs such as: Totan 200WP, Ychatot 900SP, Xanthomix 20WP...
* In order for spring vegetables to be economically efficient, at this time, farmers need to prevent and control high density of silkworms, green worms, flea beetles on cruciferous vegetables, fruit borers, aphids, thrips that damage beans and cucumbers with biological drugs such as: Aizabin WP, Vi - BT, Bitadin WP, VK. Areas specializing in cruciferous vegetables where high density flea beetles frequently appear need to apply crop rotation measures with other vegetable groups, pump water to soak the soil to kill larvae in the soil before planting the new crop. Late blight on eggplants, downy mildew on cucumbers, beans, etc. need to be prevented with Nano silver, Nano copper preparations during the harvest period or use Phytocide 50WP, Insuran 50WG, etc. during the period when the plants develop biomass.
