Black-spot pest control technology

Blackberry is one of the third-generation fruits recommended by the World Food and Agriculture Organization (FAO) in 1993 to the world. In 1995, it was introduced from the United States by Xuecheng Xingnong Seed Company, Zaozhuang City, Shandong Province. In 1997, it was listed as a key agricultural promotion project by the Municipal Science and Technology Commission and the Municipal Bureau of Finance. Due to its good nutrition and unique flavor, it is suitable for fresh food and processing of fruit juices and canned foods. The supply of fruit is in short supply. Blackberry has fewer pests and diseases, and its occurrence is light. Field cultivation generally does not require pesticides, and thus it has become a popular "green food." In recent years, the blackberry production park in Nanshi Town, Xuecheng District, has found that spotted mustards harm BlackBerry in varying degrees. Now the hazards and control technologies of spotted mustards in the Blackberry Garden are briefly described as follows:

Occurrence of hazards: Spotted mandarin ducks occur for 3 generations a year, and the adults spend their winters in litter, root seams, gaps in buildings nearer to the Blackberry Park, and gaps in the leeks between the bark gaps. After the winter, he moved to the Blackberry Garden one after another in mid-May and completed two generations on the Blackberry. May-July is the height of the damage. Adult nymphs like to inhabit in the ear to suck juice, and sometimes there is a long, nymph-fighting phenomenon on a fruit. In April-May, spotted beards harm plant shoots, causing young leaves to die and new shoots to “break”. The tender young fruit is damaged, causing the fruit to grow abnormally and become a deformed fruit. The mature fruit was sucked into the juice, and the fruit on the sunny day was wilting and the fruit was dull; the fruit particles in the event of rain faded and deteriorated and became white fruit, and the taste became worse, losing the commodity value. Generally caused by a 5% reduction in production, serious up to about 15%.

Prevention and control technology: In April and May, the prevention and treatment of spotted beards that harm young shoots, buds, and leaves can be controlled with 40% omethoate 1500-2000 times liquid spray.

In the early fruit ripening period (June-July), spotted beards and nymphs are perched between the ears, and when the density reaches 2 heads/panicles for control, high-efficiency, low-toxic, low-residue pesticides should be used for prevention and control. The liquid is evenly sprayed on the ear. If 80% dichlorvos 2000-3000 times to control, pay attention to more than 3 days before harvest; if using 90% crystal trichlorfon 800-1200 times to control, it should be more than 7 days before harvest. If it is controlled with 20% of hydrogen empyrene emulsifiable concentrate 3000-5000 times or 20% of chlorsulfuron 3000-4000 times, it must be controlled 15-20 days before harvest to ensure that when the fruit is harvested Safety, control effect is generally more than 85%.
