Cover guava fruit with nylon bag to prevent pests

The use of plastic bags, paper bags or bags used to cover fruits and prevent harmful pests has been applied for a long time by some countries in the region and obtained good results; not only restraining a number of specialized pests and diseases, but also making the pods bright, beautiful and attractive to consumers.

With guava trees, the Mekong Delta scientists have also conducted a number of experiments. The results showed that fruit batches were covered with nylon bags although not sprayed with pesticides, but the number of fruits was less than 2.5 to 4 times higher than those without fruit but using normal pesticides. The productivity in the fruit-bearing lot also increased 3-4 times. The fruits are covered with less pests and diseases, so the left and shiny pods are sold at a higher price.

As for how to do it, you can proceed as follows:

Use a nylon bag with a size of 15 x 20 cm, take a burning incense stick and perforate each 10-15 small holes (should be folded into a thick layer to just punch once will be many bags). Wait for 15-20 days of fruit guava (left big thumb), spray a batch of insecticide, wait 3-5 days, cover the fruit by placing the fruit in the bag and taking the tie Close your mouth. Remember to punch some holes at the bottom of the bottom of the bag, so that the water does not settle in the bag every time there is rain or watering.
