Garlic rust is a common disease, occurring in years with frequent fog and rain in autumn, severely impacting the profitability of garlic cultivation. So, what pesticides are used to treat garlic rust? Let's find out below.
1. Fluticasone
Flutriafol is highly effective against garlic rust and is the most efficient triazole fungicide . For rust control on one acre of garlic, 30-50 ml of 12.5% flutriafol suspension can be used for highly effective sterilization, resolving the problem in one application.
2. Chlorobromoisocyanuric acid
Chlorobromoisocyanuric acid is effective not only against fungi, but also against bacteria and viruses. For garlic rust, it is recommended to spray with 10g of 50% chlorobromoisocyanuric acid wettable powder per bucket of water; the effect is very good.
3. Benzoic acid propiconazole
Benzoic acid and propiconazole are a combination of triazole fungicides. The combination is more effective and highly efficient in controlling rust. It can effectively control garlic rust. Use 20-30 ml of 30% benzyl propiconazole suspension per acre.
4. Sodium dichloroisocyanurate
Sodium dichloroisocyanurate is also effective in controlling rust. Its main effect on pathogens is through oxidation, rapidly eliminating them; rust powder can be removed within 24 hours. Use 40g of 40% sodium dichloroisocyanurate per acre of garlic.
5. Azoxystrobin
Azoxystrobin can also effectively control rust. In actual use, 15ml of 22.5% azoxystrobin suspension can effectively kill pathogens. However, due to its high cost, it is recommended to use it in combination with propiconazole and flutriafol to reduce the amount of azoxystrobin used.
6. Methoxyacrylate bactericides
Methoxyacrylate fungicides, such as azoxystrobin and pyraclostrobin, can also control rust. However, when using these fungicides, it is recommended to combine them with triazole fungicides, such as pyraclostrobin + flutriafol or azoxystrobin + tebuconazole. The combined use will yield better results.
