Spirotetramat has a good killing effect on small insects such as whiteflies, thrips, aphids, scale insects, pear psyllids, mealybugs, and blind bugs. It is currently the only insecticide with systemic and up-and-down conduction effects. After application, the agent can be absorbed and conducted to all parts of the plant through the leaves and phloem, which can effectively protect new leaves and flowers and fruits. The insecticide method is mainly stomach poison and contact killing, and the lasting effect is long.
Spirotetramat has a unique two-way systemic conduction characteristic and the dosage form is a suspension. Spirotetramat is effective for adults, larvae, nymphs, and eggs. It is first absorbed by the leaves, and then conducted to the roots, stems, leaves, and other parts of the plant. The agent is brought into the insect body through the insect's inhalation to kill the pest. Even if the adult lays eggs after contact with the agent, the eggs cannot hatch normally.
Common v preparations include single-dose and compound preparations. The compound preparation of abamectin and spirotetramat (4% Abamectin + 24% Spirotetramat) is recommended.
Abamectin·spirotetramat is absolutely effective in killing whiteflies, thrips, and aphids. The effect is significant and lasts for a long time. In the current economic crop areas, due to the continuous use of drugs and serious overdose, thrips, whiteflies, and aphids have developed resistance. The common phenomenon is that growers cannot kill pests, so they continue to increase the dosage of drugs, which further stimulates the resistance of pests. Abamectin·spirotetramat is a good choice in the absence of special drugs.
However, some growers reported that the effect of using spirotetramat is not very obvious. Here we have to talk about the use method and skills of spirotetramat. We have introduced at the beginning of the article that spirotetramat's main insecticide method is stomach poison. Because it has a very good two-way systemic conduction effect, the absorption of the agent is the fundamental factor that determines the insecticide effect. For example, citrus has a thick wax layer on the leaves. It is difficult to retain the liquid medicine when it falls on the leaves, resulting in insufficient absorption of the agent and failure to achieve a good insecticide effect.
Drug application skills: In order to promote the absorption of the liquid medicine, the editor has demonstrated a very good combination experimentally. Before applying the medicine, we can first add 10-15 ml of vegetable oil adjuvant per 30-40 catties of water, and then add Abamectin·Spirotetramat. It should be mentioned here that the vegetable oil adjuvant should be added to the medicine barrel and stirred evenly before adding the agent. The agent must be diluted twice. The diluted agent should be added to the already stirred vegetable oil adjuvant barrel and stirred evenly again.
After completing the above steps, you can apply the medicine. After the first application of the medicine, the second application of the medicine should be carried out 5-7 days after the insect pests are seriously infested. The effective period can be up to about 30 days.
