Embodiment 1
[0030] Embodiment 1, the preparation for controlling fruit tree aphids and spider mites is cow urine.
Embodiment 2
[0031] Example 2, the cow urine of the preparation for preventing fruit tree aphids and spider mite is cow urine fermentation liquid, and the cow urine fermentation liquid is obtained by the following method: filter the collected cow urine, remove impurities, and put it into a transparent container , fermented for 15 to 30 days at a temperature between 25 and 30 degrees Celsius.
[0032] The following is a test of the control effect of cow urine fermentation liquid on red spiders, aphids and other greenhouse flower pests:
[0033] The control effect is calculated using the following method:
[0034] Control effect
[0035] P ( % ) = ( T 0 - T n T 0 ) × ...
Embodiment 3
[0045] Example 3, the cow urine of the preparation for preventing and controlling fruit tree aphids and spider mite is the cow urine supernatant of the cow urine fermentation liquid, and the cow urine supernatant is obtained as follows: the collected cow urine is filtered to remove impurities , put into a transparent container, and ferment for 15 to 30 days at a temperature of 25 to 30 degrees Celsius. After the fermentation is completed, centrifuge at 6,000 rpm for 5 minutes at a temperature of 20 degrees Celsius to obtain the supernatant, which is cow urine supernatant.
