To get better results when spraying pesticides to kill insects, you can refer to the following two approaches:
1. Determine the control pesticide according to the type and size of the pest
Pests can be divided into aphids and planthoppers, snout moths, spiders, beetles, etc. Different types of pests require different pesticides. For controlling aphids, it is best to use pesticides with strong systemic action such as methomyl and imidacloprid. For controlling leaf-eating pests such as snout moths, it is best to use pesticides such as diflubenzuron. When pests are young, using a single pesticide works very well. After the 3rd instar, two or more pesticides must be used in combination. Adding a penetrant at a certain concentration will produce even better results.
2. Determine the application method according to the characteristics of the pest
Some pests lay eggs on the leaf surface, while others lay eggs on the underside of leaves; some prefer to feed on tender leaves, while others prefer old leaves; some are active on the upper part of the plant, while others are active on the lower part; some prefer to feed during the day, while others prefer to feed in the evening. When controlling them, use the corresponding spraying method according to the above characteristics, and you will achieve better control results.
