Embodiment 1

[0030] Example 1 Field Control Test of Mango Dew Spots from Young Fruit Stage to Expanding Stage

[0031] The composition containing organic matter was formulated into water emulsion, and the dew spot field test was carried out from the young fruit stage to the expansion stage of mango with the composition, and a corresponding control was set up, and 3 adult Guifei mango trees were selected for each agent. In the young fruit stage (30 days after flowering) and the fruit expansion stage (60 days after flowering) respectively, use a knapsack sprayer to apply pesticides at a constant rate, and each plant is divided into east, south, west, north, and south 5-7 days after the second medicine. Sampling at five points. 10 fruits were randomly investigated at each point, and the total number of investigated fruits and the number of diseased fruits were recorded. The control effect of mango dew water spots is calculated according to the following method.

[0040] Example 2 Field Test of Composition Containing Organic Matter to Control Mango Dew Spots in Ripe Stage

[0041] The composition containing organic matter was formulated into a suspension agent, and the composition was used to carry out a field test of mango dew spots in the mature stage, and a corresponding control was set up, and 3 adult Guifei mango trees were selected for each agent. Before the medicine, each plant was sampled according to the five points of east, south, west, north, and middle, and 10 fruits per plant were investigated and put on the list. The knapsack sprayer was chosen to apply the medicine at a constant rate 20 days before harvest, and it was investigated and listed 5 days after the medicine. For processing, record the total number of investigated fruits and the number of diseased fruits at all levels. Calculate the mango dew spot disease index and control effect according to the following grading method.

Abstract

The invention belongs to the field of agriculture and relates to an organic-matter containing agricultural composition and use thereof. An organic matter is chitin or a degradation product thereof, and the composition generally contains one or more of an adjuvant, a carrier and a surfactant. The composition also contains active ingredients, i.e., one or more of an element fertilizer, amino acid and a bactericide, the mass percent ratio of the organic matter to the active ingredients is (30: 1) to (1: 30), and the total content of the organic matter and the active ingredients accounts for 0 to 90% the total weight of the composition. The composition has the uses of controlling diseases and insect pests, promoting fruit coloring and prolonging a harvested shelf life and particularly has a good effect on the prevention and treatment of dew spots of mangoes.

Description

technical field [0001] The invention belongs to the field of agriculture, and relates to an agricultural composition containing organic matter and its use, especially the use of chitin and chitin degradation products for preventing and treating mango dew spots. Background technique [0002] Mango is the popular name of mango (Flora of China), a well-known tropical fruit widely planted in tropical and subtropical regions. Hainan Province is one of the main producing areas of mango in my country, and Guangdong is also cultivated as a cash crop. , Guangxi, Sichuan, Fujian, Yunnan, Taiwan and other provinces and regions, the mango industry has become one of the important agricultural pillar industries in hot areas. The fruit contains sugar, protein, and crude fiber. The precursor carotene of vitamin A contained in mango is particularly high, and the content of vitamin C is not low. Minerals, proteins, fats, sugars, etc. are also its main nutrients. It can be used to make fruit j...
