A good systemic mixture for downy mildew.

Propamocarb is a locally systemic, low-toxic fungicide with specific effects on the Oomycetes. It inhibits the biosynthesis of phospholipids and fatty acids in the cell membrane of pathogens, thereby inhibiting mycelial growth, sporangia formation and germination. Due to its different mechanism from other types of fungicides, there is no cross-resistance. After application, the pesticide can be quickly absorbed by the leaves and dispersed and the protective effect can be functioned within half an hour. At the same time, propamocarb has a significant growth-promoting effect on the roots, stems and leaves of crops.
 
Fosetyl acts as a foliar fungicide with protective and curative action. It has a contact and local systemic activity and also inhibits sporulation. It can effectively control many diseases caused by Phytophthora, Pythium, Peronospora in horticultural crops such as grapes, strawberries and onions.
 
The mixture of Propamocarb and Fosetyl can significantly improve the efficacy and reduce the resistance caused by single formulation use. Inter-China spent a lot of energy on this formulation development and field efficacy. We entrusted Pesticide Research Institute and Academy of Agricultural Sciences to conduct the field trials on cucumber and grape downy mildew, respectively. It can be seen that our product can increase the control efficiency the downy mildew on cucumber, especially on grape compared to single Propamocarb and the mixture from the other company’s.

It can be concluded that the control efficiency of Inter-China product can reach 89.59% at the dosage of 2.5L/ha, which is greatly higher than that from the
Now we have already got registration of Propamocarb 530g/L+Fosetyl 310g/L SL in central American countries like Panama and Nicaragua. Considering this product is widely used in Andean Community countries(Fig.3), we will enter more countries like Peru, Colombia and Bolivia., etc.

note
1. When preparing, dilute the recommended dosage with a small amount of water in a clean container, and then transfer it all to the sprayer, and then add enough water and mix it thoroughly.
2. Do not mix with alkaline pesticides.
3. Apply three times at most for every crop cycle.
