Common Aphid Atlas for Flowers
Today, I will explain in detail the relevant experience of flower clinics for netizens, the common aphid atlas for flowers, and the specific content is as follows:
I. Aphid Type
The most common pest in flowers is the aphid. Aphids are a general term for insects of the order Homoptera and the Aphididae family. They are small in size and are divided into winged, wingless, sexual, and asexual types. They have a piercing-sucking mouthparts that pierce into the tender tissues of plants to absorb sap and can secrete "honeydew". They have more than 10 generations per year. There are many species,危害 grain, cotton, vegetables, fruits, tobacco, and more than 100 other plant species. For example, wheat aphids, sorghum aphids, cotton aphids, vegetable aphids, peach aphids, etc.
The following is a common occurrence of aphids on a type of flower. I hope everyone can learn from one case to prevent and control aphids in household flowers. In southern regions, aphids can occur almost all year round, with the peak periods being March to April in spring and June to July in summer. It is necessary to pay special attention to observe the pest situation.
Aphid Control:
I. Selection of Pesticides: 1. Spray 10% imidacloprid wettable powder 1000-1500 times liquid; 2. Spray 20% carbosulfan (Good Year Winter) emulsifiable oil 1000-1500 times liquid; 3. Spray 50% fenvalerate 1500 times liquid; any one of the above methods can be chosen, and there are also many other pesticides such as cypermethrin, aphid net, etc., that can be used for control. However, imidacloprid should be the first choice because it has the characteristics of high efficiency, low toxicity, broad-spectrum, systemic, and long-term efficacy.
II. Method: Since aphids often occur on the back of leaves, tender branches, and flower buds, the upper part of the branches and the back of leaves should be emphasized during spraying, and the mist droplets should be fine and evenly sprayed.
Special attention should be paid to the fact that some aphids have a certain specificity, such as the Hangzhou Xinxiang aphid in Figure IV, which mainly harms the insect-resistant tree and forms galls on the leaves, which requires special attention.
