Copper oxichloride spray is a useful crop protection method utilized by paddy farmers. As paddy fields are highly prone to fungal and bacterial infections, adequate protection measures are vital to safeguard the yield. Copper oxichloride is a broad-spectrum fungicide that helps in controlling a range of fungal and bacterial diseases in paddy crops.
The copper oxichloride spray dose varies depending on the severity of the infection and the stage of paddy growth. However, the commonly recommended spray volume is 0.2% of copper oxichloride. The recommended dosage is about 200 grams per acre or 500 grams per hectare. It is essential to follow the manufacturer’s instructions while using copper oxichloride spray.
The application of copper oxichloride spray should commence about two weeks after seedling transplantation. The first spray should be done before the appearance of any visible signs of disease. Subsequently, spraying should be done at regular intervals of 10-14 days until the flowering stage. It is advisable to avoid spraying during the flowering stage as it may lead to decreased pollination.
It is essential to note that copper oxichloride spray may cause phytotoxicity at higher doses. Additionally, the spray should not be applied during rainy weather as it may get washed away and become ineffective. Hence, it is vital to apply the spray during sunny weather conditions.
In conclusion, the copper oxichloride spray dose for paddy varies based on multiple factors, such as crop stage and disease severity. Farmers should follow the manufacturer’s instructions while using copper oxichloride spray to prevent any phytotoxicity and ensure optimal crop protection. It is also necessary to avoid spraying during flowering and rainy weather conditions. Adequate protection measures like copper oxichloride spray are vital to safeguard paddy yield and ensure food security.
