Embodiment 2

[0030] Field efficacy test method

[0031] According to the agricultural industry standard of the People's Republic of China, NY / T1464.27-2010 standard implementation.

[0032] test subject

[0033] Aphids, the experimental crop is Brassica napus.

[0034] Selection of test fields

[0035] The experimental field is the rapeseed field in Fanchang County, Wuhu City, Anhui Province. Fields with consistent soil fertility, severe aphid occurrence, and consistent damage were selected for the experiment.

[0036] Experimental group

[0037] 10% Robinia pseudoacacia seed extract emulsion in water has 2 dosage gradients: 400mL / mu and 600mL / mu; the dosage of 200 times dilution / mu of bamboo vinegar solution, and the dosage of 400 times dilution / mu of bamboo vinegar solution. At the same time, 80 mL / mu of plant source contrast agent 0.5% veratrine soluble liquid was set. As well as the water control, each treatment was repeated 3 times. The area of ​​the experimental plot is 20m2 , ...

Abstract

The invention relates to a synergist for a botanical aphicide, and belongs to the technical field of aphicides. A bamboo pyroligneous liquid has a synergistic effect on the botanical aphicide containing a Robinia pseudoacacia seed extract and can also be used as a synergist. Compared with a chemical pesticide, a botanical pesticide has the characteristics of slow pesticide effect, low activity and the like, so that the adding of the pesticide synergist is one of main methods for improving the pesticide effect of the botanical pesticide. The synergist shows that a solution of the bamboo pyroligneous liquid diluted by 100-400 times has a synergistic effect on the botanical aphicide based on the Robinia pseudoacacia seed extract, and the synergistic effect is verified through indoor toxicity tests and field pesticide effect experiments; the independently researched and developed botanical aphicide and the bamboo pyroligneous liquid are both from plant materials, have characteristics of being easily degradable, pollution-free, safe and efficient, therefore, a novel effective solution can be provided for high-value-added agricultural products such as green and organic fruit and vegetables and the like.

Description

technical field [0001] The invention belongs to the technical field of aphidicides, and in particular relates to a synergist of botanical aphidicides. Background technique [0002] Bamboo vinegar is a tan liquid with a smoky smell, which is formed by pyrolyzing bamboo processing waste as raw material, containing acids, phenols, aldehydes, ketones, esters and other compounds. The review of literature shows that bamboo vinegar itself has the functions of regulating plant growth, inhibiting bacteria, killing insects, improving soil fertility and so on. Bamboo vinegar is widely used in the fields of daily chemicals, health care products, feed, beverage, medicine and agriculture. At present, many scholars have carried out studies on the synergistic effect of bamboo vinegar with different medicines. However, a further in-depth search shows that there is no published patent on the use of bamboo vinegar mixed with self-developed plant-derived aphidicides or used as a synergist of ...
