This invention discloses a pesticide composition for controlling guava nematodes and its preparation method, belonging to the field of pesticide technology. By weight, the raw materials of the pesticide composition include the following components: 8-12 parts of neem seed extract, 8-12 parts of pyrethrum extract, 5-8 parts of tongkat ali extract, 5-8 parts of croton fruit peel extract, 5-8 parts of guava leaf extract, 20-25 parts of compound microbial agent, 3-5 parts of sodium lignosulfonate, 5-8 parts of xanthan gum, 4-6 parts of trehalose, and 80-100 parts of water. The above components work synergistically to achieve excellent control of guava nematodes.

The present invention relates to a method for preparing a fermented guava leaf composition having antioxidant efficacy superior to that of conventional guava leaves by using lactic acid bacteria fermentation in a guava leaf extract. The present invention has an excellent effect of providing: the method for preparing a guava leaf composition fermented with lactic acid bacteria, in which lactic acid bacteria of Leuconostoc mesenteroides (MGE 3138), Lactobacillus plantarum (MGE 3143), and Leuconostoc citrium Cares-1 are inoculated into a guava leaf extract and fermented; and a food composition having improved antioxidant efficacy and palatability by using the composition.

The invention aims to provide a new application of a guava leaf extract for indications, and particularly relates to a new application of the guava leaf extract for treating nervous system degenerative diseases, Parkinson's disease, anti-aging (used for medicines with beauty and health care effects), amyotrophic lateral sclerosis and metabolic diseases, and an effect of the guava leaf extract in brain nerve protection.

The invention provides a fried food wrapping material and application thereof.The fried food wrapping material comprises slurry powder and wrapping powder, the slurry powder comprises functional components and basic components, the functional components comprise phytic acid, bamboo leaf extract, guava leaf extract and D-sodium erythorbate, and the basic components comprise starch, flour, oil, a leavening agent and a thickening agent. The wrapping powder comprises starch, flour, oil and a leavening agent, and the mass ratio of the slurry powder to the wrapping powder is 1: (0.85-1.05). The phytic acid can fundamentally cut off fat oxidation and Maillard reaction paths catalyzed by metal ions such as Fe < 2 + > and the like, the bamboo leaf extract and the guava leaf extract can directly terminate an oxidation reaction chain, the D-sodium erythorbate can consume oxygen in a system and create a low-oxygen environment, and the four components have a synergistic effect of chelation, removal and isolation, so that the effect of reducing the oxygen content in the system is achieved. Therefore, the product can still keep stable and attractive golden yellow after being frozen and fried again, and the phenomenon that the color is too deep or blackened is avoided.

The invention discloses a composite medicament for promoting flower and fruit retention of ruby guava and a preparation method thereof, and belongs to the technical field of pesticides. The composite agent comprises the following raw material components in parts by mass: 10-15 parts of a kelp extract, 5-10 parts of a rape pollen extract, 5-10 parts of a guava leaf extract, 5-8 parts of amino acid chelated trace elements, 5-8 parts of a composite microbial agent, 3-5 parts of sodium lignin sulfonate, 3-5 parts of chitosan and 80-100 parts of water, the amino acid chelated trace elements are chelates of iron, zinc, potassium, calcium, boron and amino acids. The components have a synergistic effect, so that the flower and fruit retention effect of the ruby guava can be effectively promoted.
