Description
Technical Field
The invention relates to the field of pesticides, and particularly relates to a compound pesticide for controlling lygus lucorum.
Background
Apolygus lucorum (Meyer-D ü r) belongs to the order Hemiptera (Hemiptera), Apolygus (Miridae), Apolygus (Apolygus). Nymphs and adults of lygus lucorum prick and suck tender shoots, tender leaves, flower buds and young fruits of host plants by using a piercing-sucking mouthpart to carry out poisoning, and the quality and the yield of agricultural products are seriously influenced.
The lygus lucorum is a polyphagic insect with wide host range and important host asThe plant has 28 families, is used as a main overwintering host of lygus lucorum, and after the overwintering eggs are hatched, the jujube trees are firstly damaged, and lygus lucorum becomes a new destructive pest of the current jujube trees. The adult green plant bugs mainly comprise damaged jujube leaves, flower buds and young fruits, and the phenomena that the leaves are mottled and green lost and the heads are broken seriously occur after the green plant bugs are found to be damaged jujube trees in the early investigation process. In recent years, in different areas of China, great loss of green plant bugs to date gardens is reported, in some date areas in Shandong and Hebei in 1997, large-area yield reduction is caused by the green plant bugs being harmful, more than 2000 tens of thousands of date trees are damaged by 20-30 percent and almost never produced (Zhongguang Fang, etc., 1998); in 2001, the green plant bugs in the jujube producing area of the subishi of jin Zhong city of Shanxi province are serious, the fruit drop rate of jujube trees reaches 40 percent, the weight of jujube trees reaches 70 percent, and the yield of jujubes is reduced by 30 to 60 percent (Jordan, 2004, etc.); in 2003, lygus lucorum seriously occurs on jujube trees in great city county in Hebei province, and the occurrence area is 10 ten thousand mu. The jujube trees are greatly reduced in yield and even completely harvested in the jujube area of Cangzhou city in Hebei province. In 2008, the damage rate of the head of the winter jujube in the Tianjin part jujube garden reaches 88.7 percent, the damage rate of the hanging jujube reaches 87.5 percent, and the damage rate of the leaves reaches 77.5 percent (Liutao, 2010). 2013, 2014 the green plant bug is harmful, which results in 5.33 ten thousand hm in the whole county of Shanxi Jia county2The jujube forest has the yield reduction of 60 percent and 75 percent respectively (Liailin, 2016). In recent years, lygus lucorum has become the most serious pest of Shanxi jujube tree over cardiotrophin, and the yield damage rate of jujube in the serious year of Shanxi county is 80% -100% (Cupheliforme, 2016).
The use of pesticides is a main measure for preventing and controlling diseases, insects and weeds of crops, but only a few parts of the pesticides sprayed by spraying treatment can reach a control target, and Metcalf (1980) estimates that only 25-50% of the pesticides sprayed by a pesticide application instrument can be deposited on crop leaves, less than 1% of the pesticides are deposited on target pests, and only less than 0.03% of the pesticides which really have the insecticidal action. Thus, chemical pesticides are highly effective, but are less effective. The low-efficiency use of the pesticide not only wastes a large amount of pesticide, but also causes the pesticide to be lost into a non-target environment in a large amount, thereby causing the problems of poisoning human beings and livestock, environmental pollution and the like. How to effectively utilize the pesticide and reduce the dosage of the pesticide in a non-standard environment becomes a problem which is urgently needed to be solved by the pesticide science (Yuanzhu et al, 2001).
The green plant bug has strong mobility and high concealment, the probability of direct contact of spray with insect bodies is low, and most pesticides have short duration, so the application dosage is high, the times are many, the environmental impact is large, and the pest control effect of natural enemies is reduced. For this reason, a new technology for continuously and effectively controlling lygus lucorum is urgently sought.
