Problems solved by technology

[0003] At present, the production still mainly relies on the chemical control of the vector insect thrips to achieve the prevention and control of spotted wilt virus, which has caused the unreasonable use or even abuse of chemical insecticides, which in turn leads to pest resistance and insecticide pollution. and residues, seriously threatening the safety and ecological security of agricultural products, as well as major social and economic issues such as the export of agricultural products
[0004] At the same time, the current common insect-proof net with good ventilation effect is difficult to block thrips from entering and leaving the greenhouse
The use of no less than 60-mesh insect-proof net has seriously affected the ventilation effect of the greenhouse. The ventilation speed is slow and the cooling speed of the greenhouse is slow, which affects the growth of tomatoes and aggravates the occurrence of viral diseases. If you choose a 40-mesh ordinary insect-proof net with better ventilation effect, it will not be able to block Thrips in and out of the greenhouse, the effect of isolating thrips is not achieved

Embodiment 1

[0033] Example 1: Tomatoes were cultivated in a solar greenhouse with delayed cropping in autumn. Tomatoes were cultivated in rows in a solar greenhouse according to size, with a large row spacing of 80 cm, a small row spacing of 60 cm, and a plant spacing of 40 cm.

[0034] Transplant kale 10-12 days before tomato planting; plant a row of kale in the middle of the planting row, with a plant spacing of 25cm; open holes for planting, and apply 75g of carbonized rice husk to each hole, and plant the kale seedlings in the holes.

[0035] The seedlings of kale are raised in plug trays, and the substrate is composed of peat: carbonized rice husk: vermiculite in a volume ratio of 2:1:1. Kale is 30-35 days earlier than tomato, and kale is 50 days before transplanting. Add 12.5 g of dinotefuran water-dispersible granules to 30 kg of water and dip in the plug tray, so that the matrix in the plug tray is completely soaked by the medicinal solution.

[0036] Before transplanting the kale...

Embodiment 2

[0052] Example 2, tomato was cultivated in autumn delayed stubble in a solar greenhouse at a certain vegetable base in Shouguang, Shandong. Sowed on July 11, 2015, and planted on August 18, the variety is FA-1420, which is not resistant to spotted wilt virus. There are 2 treatments in the experiment, except for the required measures, other management measures are exactly the same.

[0053] Processing 1: Carry out according to the technical scheme of embodiment 1.

[0054] Treatment 2: Tomatoes are cultivated according to the following method, the air vents of the solar greenhouse are covered with insect-proof nets, and existing chemical methods are used to prevent and control thrips vectors of spotted wilt virus disease. The concrete technical scheme is as follows: the air vent of the solar greenhouse is closed with a 60-purpose common insect-proof net. When transplanting tomatoes, use 12.5g of 50% dinotefuran water-dispersible granules mixed with 30kg of water to dip the ho...

Embodiment 3

[0058] Example 3, tomato was cultivated in a solar greenhouse with delayed stubble in autumn, and the location was in a vegetable base in Shouguang, Shandong. It was sown on June 28, 2015, and planted on July 24. The variety is Provence, which is not resistant to spotted wilt virus. There are 4 treatments in the experiment, except for the required measures, other management measures are exactly the same.

[0059] Processing 1: Carry out according to the technical scheme of embodiment 1.

[0060] Treatment 2: Except that the substrate for kale seedlings is peat: vermiculite at a volume ratio of 3:1 and carbonized rice husks are not mixed in the kale planting hole, other measures are the same as treatment 1.

[0061] Treatment 3: Except that the mixed aqueous solution of fennel extract and chitin is not sprayed on tomato seedlings 1-2 days before planting, and the mixed aqueous solution of fennel extract and chitin is not sprayed on the leaves 35 days after tomato planting, oth...

Abstract

The invention discloses a prevention and treatment method for tomato spotted wilt virus. According to the invention, tomato is cultivated in a solar greenhouse according to large and small rows, wherein large row spacing is 80 cm, and small row spacing is 60 cm; kale is transplanted in 10 to 12 days before field planting of the tomato, wherein a row of the kale is planted in the middle of a smallplanting row, and plant spacing is 25 cm; a carbonized rice husk contained substrate is adopted for seedling raising of the kale in plugs, wherein carbonized rice husk is additionally applied into a planting plug, and a dinotefuran pesticidal liquid is adopted for plug dipping and root irrigation; and before the kale is transplanted, a 40-mesh pesticidal protection screen is used to seal a ventilation opening of the solar greenhouse. The prevention and treatment method provided by the invention can effectively reduce the incident rate of the tomato spotted wilt virus on the premises of greatlyreducing the usage amount of a chemical pesticide and realizing non-contact chemical prevention and treatment for a main crop, wherein the incident rate of the tomato spotted wilt virus of an infected tomato variety can be generally controlled within 4%.

Description

technical field [0001] The invention relates to a method for preventing and controlling tomato diseases, in particular to a method for preventing and controlling tomato spotted wilt virus disease which can reduce the amount of chemical pesticides used and realize non-contact chemical control of main crops. The field of plant protection technology. Background technique [0002] Tomato spotted wilt virus (Tomato spotted wilt virus) is an important plant virus that endangers agricultural production. Tomato spotted wilt virus is an insect-borne virus disease transmitted by thrips. Its control is different from that of fungi and bacteria. It is necessary to control the spotted wilt virus itself and control the vector insect thrips to control the virus. The spread and prevalence of diseases require complex and difficult control strategies. As the main cultivation crop of tomato in solar greenhouse, autumn delayed tomato spotted wilt virus disease is very serious. [0003] At pr...
