Application Technology

Banana

After the banana is harvested at the eighth maturity, the fruit without injury is soaked in 333-500mg/L prochloraz solution or 133-200mg/L prochloraz compound with the same concentration of isobutylurea solution for 2min. After being picked up, it is dried and stored, which can prevent and control banana crown rot and increase storage.

Citrus

After harvesting at maturity, select the fruits without injury, immerse the fruits in 250-500mg/L prochloraz solution, or 180-225mg/L prochloraz solution with 4-5mg/L chitosan solution, or 150-200mg/L prochloraz solution with 25-33mg/L imazole solution for 1-2min, and then remove them and dry them for storage, which can prevent and control root rot, anthrax and mildew, and increase the storage capacity.

Mango

After harvesting at the eighth maturity, select the fruits without injury and immerse them in 500-1000mg/L medicinal solution for 1min. After picking them up, dry them and store them. It can prevent anthrax and mildew and increase the storage capacity.

Sugar orange

After harvest, the fruits were soaked with 1500-2000mg/L medicinal solution for 1min, which had a significant effect on the Postharvest preservation of sugar orange fruits. The decay rates of fruits stored at room temperature for 15d, 30d, 45d, 60d and 90d were 0.5%, 10%, 10% and 30% respectively.

Orange

The fruit was soaked in 500mg/L solution for 1min and stored at low temperature. The rotten fruit rate was 11.6% when stored at 8-10 ℃ for 60 days, and the rotten fruit rate of the blank control was 62%, which greatly improved the storage property.

Gonggan

After harvest, the fruit was soaked with 2000-3000 mg/L medicinal solution for 1 min. the fruit decay rate was less than 5% after 30 days of storage at room temperature, less than 10% after 60 days of storage, and less than 15% after 90 days of storage.

Guava

After fruit picking, soak the fruit with 500-1000mg/L medicinal solution for 2min, dry it, use fresh-keeping bags to pack the single fruit and store it at low temperature of about 10 ℃, and the good fruit rate can reach 100%.

Mushroom

White rot and brown rot can be prevented by mixing 0.4-0.6g/m2 in the covered soil or spraying mushroom bed.

Precautions
