[0042] Example 1 Preparation of pesticides containing extracts of saffron apple and serrata

[0043] Preparation:

[0044] a. Extraction: Weigh the dried saffron apple leaves and serrata roots, mix, crush, pass through an 80-mesh sieve, add the extraction solution, reflux for extraction twice, filter, combine the filtrate, and concentrate to make the weight of the extract equal to the original medicinal material Lm-01~lm-06 are obtained from the weight of, and the parameters are shown in Table 1;

[0045] b. Formulation: Add the additives in Table 2 to the extracts lm-01 to lm-06, stir evenly to obtain pesticides LM-01 to LM-06 containing extracts of saffron apple and serrata.

Abstract

The invention relates to the field of pesticides, in particular to a pesticide containing Annona reticulata and derris elliptica extracts, and a preparation method and application thereof. Active ingredients of the pesticide containing the Annona reticulata and derris elliptica extracts are extracted from 1 weight part of Annona reticulata and 1 to 8 weight parts of derris elliptica. The pesticide containing the Annona reticulata and derris elliptica extracts has a synergistic effect, has an obvious effect of controlling Lepidoptera pests, can strengthen immune systems of plants while quickly killing the pests, and can obviously improve plant vitality; the pesticide is prepared from Chinese herbal medicines, so the problem of pesticide residue is solved and the pests hardly generate resistance; during use, the effective concentration is low and the cost is low.

Description

Technical field [0001] The invention relates to the field of agricultural pesticides, in particular to a pesticide containing extracts of saffron apple and serrata and its preparation method and application. Background technique [0002] In recent years, in the field of agriculture and forestry, plant diseases and insect pests have developed different degrees of resistance due to single use of drugs and unscientific use of drugs. However, chemical pesticides are still the main control species in agroforestry production, which has caused environmental pollution and increasing damage to the ecological environment. With the improvement of people’s living standards and the enhancement of health awareness, the research and development of biological pesticides is gradually receiving the attention of pesticide research and development workers, and has become a hot spot for sustainable development of agriculture and forestry. At the same time, it is also improving the environment and redu...
