Composite resistance inducer for preventing and treating early spot leaf cast of actinidia chinensis in southern region preparation method and application of composite resistance inducer

Abstract

The invention discloses a composite resistance inducer for preventing and treating early spot leaf cast of actinidia chinensis in southern regions. The composite resistance inducer is prepared from the following raw materials in percentage by mass: 0.05-0.06% of amino-oligosaccharin, 0.05-0.06% of a nutritional supplement, 0.02-0.03% of brassinolide, 0.02-0.03% of sulfur powder, 10-15% of a nitraria davidii water extract and the balance of water. According to the invention, the botanical disease-resistant composite resistance inducer for replacing chemical pesticides to prevent and control the early spot leaf cast of the kiwi fruits is creatively researched and developed, and is sprayed to the back surfaces of kiwi fruit leaves at June 1-15 every year when the early spot leaf cast of the kiwi fruits does not have obvious symptoms, so that plants obtain systematic disease resistance, and the purpose of preventing and controlling diseases in advance is achieved; and the composite resistance inducer can improve the disease resistance of kiwi fruits, can effectively reduce the morbidity and disease index of early spot leaf cast of kiwi fruits, reduces the use of pesticides, and improves the food quality safety of kiwi fruits.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of fruit and vegetable diseases and insect pests, and in particular relates to a compound inducer for preventing and treating Hongyang kiwifruit spot early defoliation disease in the southern region, a preparation method and an application thereof. Background technique [0002] Kiwi fruit (Actinidia) is one of the important types of fruits, rich in nutrition, its fruit is tender and juicy, delicious in fragrance, sweet and sour, and extremely rich in nutrition. Its vitamin C content is high, which is several times or even dozens of times higher than that of oranges, apples and other fruits. It also contains a lot of sugar, protein, amino acids and other organic substances and various minerals necessary for the human body. It is known as the king of fruits. reputation. [0003] In recent years, with the continuous development of the kiwi fruit planting industry, the problem of disea...

AI Technical Summary

Problems solved by technology

[0005] First, due to the addition of two kiwifruits or kiwifruits next to the Hongyang kiwifruit, it undoubtedly occupied the row spacing of the Hongyang kiwifruit, and the number of plants planted per mu increased by 2 times, which made the kiwifruit orchard more comfortable and airy. The light transmittance is poor, which indirectly induces the occurrence of other diseases and insect pests; at the same time, the newly added kiwifruit or kiwifruit competes with the original Hongyang kiwifruit for nutrition, which increases the cost of planting and management

[0006] Second, although this method is very similar to that described in the present invention in terms of the description of the damage symptoms of Hongyang kiwifruit, the patent application CN201110416242.5 does not know whether the disease is caused by the same cause of disease or early leaf fall caused by the same pathogenic bacteria. research
