Four beans, also known as beans, wings, quadrants, etc., enjoy the "good name of green gold" of a year's life or years' life entangled around the vine. It originated in countries like papua new guinea, myanmar, sumatra, with tropical rainforest climates, and it was only in the nineteenth century that it was introduced into our country to plant it, which is edible, leaves, buds, seeds and underground roots, and contains abundant proteins, amino acids, as well as plant resins, a variety of mineral elements and nutrients。
It is also difficult to grow with such a high value of prism, which, in addition to adapting to the surrounding natural environment, needs to be protected from pests and pests; and it is common for the fungus or bacteria-infested quadrants to suffer from stunted growth in the leaves, roots and nuts, leading to a decline in yields, among which is a disease that is seriously harmful to the nuts. On the basis of the experience of the past planting of prunes, the fight against “gourosis” has had a more visible effect on the application of a combination of strategies to strengthen field management, to combat vermin pests and to spray chemicals; this article is presented by swallows in terms of the identification of “gourosis”, the pattern of disease, and the methods used to combat it。
I. What's a triatomy
Triple bean scab is a fungi disease that causes the decomposition and atrophy of cucumbers as a result of the infestation of the tremolite organs by the mutated and spicy fungus in the semi-accumulatory amonella。
An intermediate strain is a fungus of three colours, white, rose-coloured, light-loved fungus, which produces a larger number of eggs or elliptical small spores, and a large sickle-shaped spasm; the shape of a stale is similar to that of an intermediate scab of a string, but it is colourless and can produce large scabs of a scavenger or scavenger. The size of the two fungi is not more than 24. 8 to 52. 8 x 2. 7 to 4 micrometres, and our naked eyes are invisible and can only be identified by the surface symptoms of the berries。
The disease causes the casserole to rot and to shrink
Ii. How to recognize triatomy
The effect of fungi disease in the later stages of the disease is very low, so we need to have a detailed understanding of the initial symptoms of the disease and its development. With this knowledge point, we will be able to judge whether or not it is a disease of scavenging fruit when there is stunting in our home-planted prunes。
Chrysotiles infected with fungi produce water leachate in the early stages of infection. The pace of the disease is fast, and many times when we discover it, it becomes brown; if it is not managed in a timely manner, it expands on its own mid-point, leading to an ever-larger incidence on the nuts。
When the field is more humid, white or pink molds grow on the disease, the area of the disease is larger when it is severe, and dehydration or decomposition occurs in the case of the acne. The disease is smaller and rapidly developing, and the whole acacia is rapidly shrinking and smaller; the disease is larger and, when it is severe, it causes a contraction and decay in its parts。

Paths to transmission of pathogens and conditions for the occurrence of curing diseases
An intermediate mutation and acupuncture hide winter in the form of a fungus filament or fungus nuclei in a sick strain or soil. When the root roots of our seeds are planted in the spring, they enter from the root or from the end of the wound, causing the disease of the quadrant plant and the disease of the berries, the first infection of the fungus. Because the spores of the bacteria can survive in the soil for up to 10 years, they are the main source of infection。
After the infection has been completed, scabs (white or pink molds are the scabs and scabs), which can be transmitted by water flow (rain, irrigation water) and re-infect their scabs, and so on, constantly infestate them。
Road map of repeated aggression
Due to the longer life of the fungi in the soil, the amount of bacteria accumulated in the fields that are sowed is higher, making it more vulnerable to serious and uncontrollable conditions. The bacteria are suitable for growth and reproduction in a highly wet environment, so that when the field is more humid, the disease is more severe。
Four, do three points to fight the triatoma
1. Controlling field moisture and not providing an environment conducive to the survival of pathogens
2. Prevention and control of vermin pests and improvement of the resistance of berries to disease
The larvae of the larvae of the larvae, and the larvae of the soybeans, provide favourable conditions for the larvae of the fungus, which causes the soybeans to be infected; therefore, during the period august-october, the larvae had more time to prepare for pest control and to avoid the serious damage caused by the soybeans。
The control of small ash butterflies can be sprayed with chemical agents such as 18 per cent bi-worming agent 300-400 times plus 90 per cent trichlorfon 800 times liquid, or 5 per cent (10 per cent) efficient use of 3,000 times liquid concentrate, or 30 per cent diocese cream 2,000-2,500 times liquid spray, or 55 per cent chlorine. Toxachloride emulsifiable concentrate 2,000 times liquid。
After the late harvest of the quarries, the residues of the strain should also be removed in a timely manner to reduce the base number of winter insects, thereby reducing the number of pests occurring in the coming year。

I'm going to spray chemicals in the early stages of the disease
Triple bean scurry is a fungus-induced disease and, because of its location in the acetate, the recommended use will kill the fungus and the agent that will protect the fruit is sprayed in the early stages of the disease。
Fifty per cent of the methyl sulphate pneumatics are 500 times more liquid, 20 per cent of the bacterium pneumatics 500 times liquid, 50 per cent of the more than humid powder 600 times liquid, and 50 per cent of the hemoveable powders 800 times liquids are optional。
Specific spraying methods: just two to three times, with an interval of about 10 days each。
Vegetable disease is the more common disease that causes damage to quartz nuts, which, when it occurs, produces spores from the spot, and continues to endanger others, leading to atrophy and decay, seriously affecting the yield and quality of quarries. It is recommended to prevent the occurrence of diseases early in the planting of prisms at home, to prepare for agricultural and pest control efforts, and to prevent them effectively in combination with chemical agents, in order to better reduce the occurrence of diseases。
I'm a swallow. I'm focused on crop disease and pest control。
