Embodiment Construction

[0009] Examples of controlling cucumber aphid damage in facility cucumbers:

[0010] Chrysanthemum chrysanthemum was planted on February 10, and planted in cucumber production greenhouses on March 1 (at this time, the plant height of Chrysanthemum chrysanthemum was about 12cm, and one plant was planted at about 5m, and the planting position was as follows: figure 1 . Cucumbers were planted on March 10. Aphids were found on Chrysanthemum chrysanthemum on March 12. On March 25, the number of aphids on some Chrysanthemum chrysanthemums reached 2-3 heads / cm 2 At this time, pymetrozine was used to spray and kill the aphids on Chrysanthemum chrysanthemum. The aphids in the cucumber growth period did not reach the control index, and no pesticides were used to control the aphids.

Abstract

The invention belongs to the agriculture technical field, and specifically relates to a method using crowndaisy chrysanthemum to control aphid on solanaceous vegetables; the method comprises the following steps: planting crowndaisy chrysanthemum before greenhouse solanaceous vegetable colonization, and allowing the crowndaisy chrysanthemum to be above 10cm when the vegetables are colonized; planting the crowndaisy chrysanthemum around the greenhouse vegetables; regularly observing aphid on the crowndaisy chrysanthemum, and using low toxicity pesticide to kill the aphid when the aphid density on the crowndaisy chrysanthemum reaches 2-3head / square cm. The novel method can trap aphid so as to reduce aphid damages on the vegetable, can reduce chemical pesticide application amount, can reduce vegetable pesticide residual exceeding standard risks, and improving vegetable product safety quality.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a method for controlling aphids on solanaceous vegetables with Chrysanthemum chrysanthemum. Background technique [0002] Aphids are important pests on vegetables cultivated in facilities, and there are several serious damage peaks every year. With the rapid expansion of the cultivated area of ​​protected vegetables in my country, the damage caused by aphids has become more and more serious. At present, chemical pesticides are mainly used to control vegetable aphids in production. This method not only has poor control effect, but also easily increases the risk of excessive pesticide residues on vegetables. Using other plants to trap aphids to protect target vegetables from aphid damage or reduce aphid damage is an urgent requirement for pollution-free vegetable production. Contents of the invention [0003] The present invention provides a method of using Ch...
