Embodiment 1

[0019] Embodiment 1: laboratory antibacterial experiment

[0020] In this example, the indoor tube-and-dish method was used to determine the effect of the pesticide composition on the pathogenic bacteria (Serratia marcescens, Serratia rubus, Erwinia cypripedes) and fungi (Fusarium oxysporum, Trichoderma fungus) of saffron bulb rot disease respectively. , Plexus erythrosum) antibacterial rate. The amounts of basic copper sulfate, mancozeb and fludioxonil per 100 g of the aqueous solution of the pesticide composition (or the PDA medium containing the pesticide composition) are shown in Table 1.

Embodiment 2

[0047] Embodiment 2: field test

[0048] With reference to the Standard of the People's Republic of China: Guidelines for Field Efficacy Tests of Pesticides (GB / T 17980.28-2000), field trials were conducted in Anji County, Huzhou City, Zhejiang Province, China.

[0049] Dissolve Bordeaux mixture wettable powder, 75 wt% mancozeb wettable powder and 2.5 wt% fludioxonil suspending agent in tap water to prepare five kinds of pesticide composition aqueous solutions. In every 100 g of pesticide composition aqueous solutions, alkaline The amounts of copper sulfate, mancozeb and fludioxonil are shown in Table 1.

[0050] (1) Control effect of saffron bulb storage period

[0051] During the harvest period of saffron bulbs, 180 saffron bulbs with a quality of 20 g and no disease were randomly selected, and 5 experimental groups were formed with five kinds of pesticide composition aqueous solutions described in Table 1, and 3 parallel groups were set for each experimental group, and tap...

Abstract

The invention relates to a pesticide composition and applications thereof in preventing and controlling saffron crocus corm rot. Active ingredients of the pesticide composition are basic chrome sulphate, mancozeb and fludioxonil, wherein the mass ratio of basic chrome sulphate, mancozeb and fludioxonil is (50-72):(27.5-82.5):(0.6-6.3). The invention also provides the applications of the pesticide composition in preventing and controlling saffron crocus corm rot. Control efficiency of the pesticide composition on saffron crocus corm rot is excellent, and the control efficiency is increased significantly compared with that of utilization of only one ingredient selected from basic chrome sulphate, mancozeb or fludioxonil.

Description

technical field [0001] The invention belongs to the field of pesticide compositions, in particular to a pesticide composition and its application in preventing and treating saffron bulb rot. Background technique [0002] Saffron is native to southern Europe and Iran, and is also cultivated in Shanghai, Zhejiang, Jiangsu, Shandong, Beijing and other places in my country. The stigma of saffron is its main medicinal part, which has the effects of promoting blood circulation and removing blood stasis, cooling blood and detoxification, relieving stagnation and calming nerves, can inhibit hepatitis virus, improve immunity, and has anticancer activity, known as "plant gold". In addition, saffron can also be used as a precious flavoring agent, natural color, spice and dye. [0003] Due to changes in farmland ecological pathways and increased resistance to plant diseases, saffron bulb rot has become the most serious disease in saffron production in recent years. From the storage per...
