Pineapple can prevent insects by placing poison bait, black light trapping and manual capture. Appropriate strategies should be selected to deal with different pests. When clearing the garden, if you encounter stubborn pests, such as crickets, you can put poison bait to kill insects. For small pests, such as grubs, the effect of trapping and killing with black light lamp is better. Human capture is generally used for low activity and visible pests, such as beetles. 1、 How can pineapple prevent insects? Pineapple can prevent insects by placing poison bait, black light trapping and manual capture. To place poison bait, first make poison bait. First fry rice bran until fragrant, and mix it with 100-200 times trichlorfon to make poison bait. Then clean the weeds around the orchard and sprinkle the poison bait on the place where crickets often haunt.
During the copulation and oviposition period of adult beetles, that is, from June to August, black light trapping or manual capture can be used to remove pests from beetles. Mixed fertilization is mainly a control method for beetle larvae and grubs. In areas where grub pests are serious, 0.5kg of carbofuran and 500kg of organic fertilizer are mixed and stirred as base fertilizer. 2、 How to maintain pineapple 1. Temperature: pineapple likes warmth and can grow in the range of 15-40 degrees, but the most suitable temperature is 24-27 degrees.
2. Water: they are quite drought tolerant plants, but they also need some water in the process of growth and development. Especially from April to August, when the growth is vigorous, we need to pay more attention to the water supply.
