Description
Technical Field
The invention belongs to the field of disease and insect pest control of fruit trees, and particularly relates to a method for controlling chronic senescence of citrus.
Background
Chronic failure of citrus (1)Tylenchulus semipenetrans) Is an important disease in the production of citrus in the world, is widely distributed in each citrus producing area in the world, and has the main pathogenIs about to be citrus hemipenetrans. The citrus hemitylenchus penetrans have tiny polypide and cannot be observed by naked eyes, and can invade into citrus fibrous roots to invade citrus root cortex, so that the development of the roots is stopped, new absorption roots are not generated any more, the supply of water and nutrients is influenced, the root system is enlarged and malformed, and symptoms such as root nodule and root knot are formed when the root system is serious; the initial symptoms of the overground part are not obvious and mainly accompanied with the phenomena of nutrient deficiency and yellowing, etc., but along with the continuous multiplication of nematodes, damaged absorption roots are gradually increased, and the phenomena of slow and chronic decline such as less treetops, small leaves, curled leaf edges, yellowing, lackluster, more flowers, less fruits, low yield and the like appear in tree crowns; the later stage shows that the seedlings do not bear fruits all the year round, the yield is seriously reduced, and branches are withered and fallen when the seedlings are seriously damaged, so that the whole plants are withered.
The method for controlling the citrus chronic failure disease comprises water flooding treatment and medicament treatment, which are respectively explained as follows:
and (3) flooding treatment: the growth and development of the citrus hemitylenchus penetrans require sufficient air, so that the citrus hemitylenchus penetrans can be irrigated with purified water in slack season, the deep water layer is kept for more than 40 days, and the second-instar larvae and eggs of the hemitylenchus penetrans die by suffocation. Theoretically, the method for preventing and treating the heminematoda not only is safe to people and livestock and not easy to cause pollution to the environment, but also has small investment. Even if the heminematoda is temporarily controlled to continue infection and spread, the crops infected with the heminematoda still cannot recover the growth vigor, which has great influence on the later yield and quality of the crops. However, in actual production, the water flooding treatment cannot achieve the effect of immediate effect, the economic benefit is low, and only can treat the symptoms and cannot treat the root causes.
And (3) preventing and treating by using a medicament: digging holes and rotten roots before the new shoots germinate and the new roots occur in the orchard in spring, digging an annular ditch with the width of 30 cm and the depth of 15-20 cm in a tree crown drip line, mixing fine sandy soil and 5-50 g of 10% fosthiazate granules for each plant, applying the mixture into the ditch, covering soil after application, and watering to moisten the soil. In the germination period and the emergence period of new shoots in autumn, the citrus rhizosphere is irrigated by using 1.0% abamectin EC 600-fold liquid and 750-fold root growth promoting agent, and the pesticide is applied for 1 time after 10 days, so that the control effect is good, and the tree vigor recovery and growth are quick. However, since the orchard self has no resistance to the chronic failure, the plants are not strong enough, and the disease resistance and stress resistance are not strong, the hemipuncture nematodes are fast to breed and spread, the early symptoms are not obvious, and the hemipuncture nematodes are attacked even seriously when discovered, and the prevention difficulty is greatly increased.
The amino-oligosaccharin is also called chitosan oligosaccharide, is an organic matter which can provide a food source for microorganisms, inhibit some plant pathogenic bacteria by promoting the growth of beneficial microorganisms in soil, and change the microbial flora of the soil. The plant growth can be stimulated, the crop and the fruits and vegetables can be increased in yield and harvest, the disease resistance and the nematode resistance of the plants are induced, a large amount of chitinase is generated under the induction of the amino-oligosaccharin of the root system of the crops, and the chitinase can erode chitin on the body surface of the nematodes, so that the nematodes invading into the plant bodies are fundamentally inhibited and killed. The fosthiazate is a main chemical component of the current nematicide, is widely applied in the market, has quick acting and strong systemic effect on the nematode, has outstanding effect on the nematode, but is easy to cause phytotoxicity when being inappropriately applied. Therefore, a proper high-efficiency nematicide needs to be screened, and by compounding fosthiazate and amino-oligosaccharin, the risk of fosthiazate phytotoxicity is relieved, the nematode resistance and disease resistance of crops are improved, the occurrence of citrus nematode diseases is reduced, misdiagnosis and misjudgment of citrus yellowing diseases are reduced, the planting benefit of citrus is improved, and the sustainable development of citrus industry is guaranteed.
Disclosure of Invention
The invention aims to provide a method for controlling chronic senescence of citrus.
In order to achieve the purpose, the invention adopts the following technical scheme:

Early prevention, reducing the occurrence probability of heminematoda; preventing and controlling diseases in the middle period, controlling the diseases in time and stopping damage in time; the growth vigor is recovered at the later stage, the damaged crops are helped to recover the healthy growth, and the loss is reduced.
In the early stage of the slow senescence disease of citrus, the symptoms are slight, the underground root system of a plant has no root nodules with the size of millet grains or only, the root system can normally absorb water and nutrition, and leaves do not wither, 9wt% oligosaccharide-fosthiazate aqueous emulsion (the ratio of 1.5wt% amino-oligosaccharide to 7.5wt% fosthiazate is 1: 5) is used in time, and the application method is that 500-1000 mL root irrigation is carried out on one mu of land;
in the middle stage of the citrus slow-aging disease, root nodules of plant roots are slightly large and many, and the root rot of dead plants occurs, under the condition, firstly, the plant plants in a field shed need to be cleaned in time, farm implements need to be wiped or disinfected in time, the disease source is cut off, the large-area spread of the disease is avoided, then 500-1000 mL of 9wt% oligosaccharide-fosthiazate aqueous emulsion (the ratio of 1.5wt% amino-oligosaccharide to 7.5wt% fosthiazate is 1: 5) is applied to each mu of irrigation roots, and the specific application amount can be adjusted according to the disease condition;
in the late stage of the disease of the citrus chronic senescence, large-area root systems of plants are blackened and rotted, and no new roots exist, and at the moment, 500-1000 mL of 9wt% oligosaccharide-fosthiazate aqueous emulsion (the ratio of 1.5wt% amino-oligosaccharide to 7.5wt% fosthiazate is 1: 5) is applied to each mu of irrigated roots, so that the nematode can be prevented and promoted to take roots.
The technical scheme of the invention has the following beneficial effects:
(1) inhibit and kill the ovum, kill the insect ovum, overcome the drug resistance and improve the insecticidal activity by 10 times.
(2) Quick action + long action combination: after 2 months, the fosthiazate in the soil can still have a lethal effect on the hemipuncture nematodes, and after 6 months, the activity of the nematodes can still be prevented.
(3) The nematode killing agent has strong root growing and root nourishing effects, promotes the meristem of root system cells, quickly increases capillary roots, promotes the root system to be developed, can restore the growth of crops through root irrigation treatment, and keeps a normal growth state, so that the loss caused by the nematode harm can be minimized.
(4) The pesticide has wide control range, can kill pests on the ground, improves the pest resistance of crops, can better control hemicycle nematode, can transmit the pesticide to the overground part of plants due to better systemic property, and has better killing function on aphids and thrips of the crops.
