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

Embodiment 1

[0029] Example 1, tomato was cultivated with delayed cropping in autumn in a solar greenhouse at a vegetable base in Shouguang, Shandong, and a variety that was not resistant to spotted wilt virus was selected. Tomatoes are cultivated in the solar greenhouse according to the size of the row, the largest row spacing is 80cm, the small row spacing is 60cm, and the plant spacing is 40cm.

[0030] Transplant kale 10-12 days before tomato planting; plant a row of kale in the middle of the small row of planting rows, 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;

[0031] 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. % dinotefuran water dispersible granules 12.5g mixed with 30kg of water dipped in th...

Embodiment 2

[0043] Example 2, tomato was cultivated in a solar greenhouse with delayed stubble in autumn, at a vegetable base in Shouguang, Shandong Province, sown on July 10, 2015, and planted on August 16. The variety is Qidali, which is not resistant to spotted wilt virus disease. There are 2 treatments in the experiment, except for the required measures, other management measures are exactly the same.

[0044] Processing 1: Carry out according to the technical scheme of embodiment 1.

[0045] Treatment 2: Cultivate tomatoes according to the conventional method of controlling spotted wilt virus disease, cover the vents of the solar greenhouse with insect-proof nets, and use existing chemical methods 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 m...

Embodiment 3

[0049] Example 3: Tomatoes were cultivated in a solar greenhouse with delayed cropping in autumn, at a vegetable base in Shouguang, Shandong Province, sown on July 20, 2015, and planted on August 25. The variety is FA-1420, which is not resistant to spotted wilt virus disease. There are 4 treatments in the experiment, except for the required measures, other management measures are exactly the same.

[0050] Processing 1: Carry out according to the technical scheme of embodiment 1.

[0051] 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.

[0052] Treatment 3: Except that the tomato seedlings are not sprayed with the mixture of new high-fat film and chitin 1-2 days before planting, and the leaves are not sprayed with the mixture of new high-fat film and chitin 35 days after tomato planting, other measures are the s...

Abstract

The invention discloses a method for preventing and controlling tomato spotted wilt viruses. The method comprises the steps: cultivating tomatoes in a sunlight greenhouse according to large and smallrows, wherein a large row spacing is 80 cm, and a small row spacing is 60 cm; transplanting collards within 10-12 days before the tomatoes are planted, planting a row of collards between small rows ofa planting row, wherein the row spacing is 25 cm; carrying out plug seedling on the collards by using a substrate containing carbonized rice hulls, additionally applying the carbonized rice hulls into planting pits, and dipping plug trays and irrigating roots by using a dinetofuran liquid; and before transplanting the collards, sealing a ventilation opening of the sunlight greenhouse by using a 40-mesh insecticidal protection net. By using the method, the incidence rate of the tomato spotted wilt viruses can be effectively reduced on the premises that the dosage of a chemical pesticide is greatly reduced and the non-contact chemical prevention and control of main cultivated crops are realized, and generally, the incidence rate of the spotted wilt viruses of susceptible tomato varieties can be controlled within 5%.

Description

technical field [0001] The invention relates to a control method for tomato diseases, in particular to a control method for tomato spotted wilt virus disease which can reduce the use of chemical pesticides and realize non-contact chemical control of main crops. It is very suitable for autumn delayed tomato cultivation in solar greenhouses and belongs to plant protect the technical field. 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...
