Description

Pesticide formulations containing spirotetramat for controlling Liriomyza and Bemisia tabaci

technical field

The invention relates to the preparation of a pesticide preparation for controlling Liriomyza sativae and whitefly, and belongs to the technical field of pesticide preparation.

Background technique

Liriomyza spp is a pest belonging to the Liriomyza family Diptera. It was introduced into my country from Brazil in 1993, and it occurs all over the country at present. Both adults and larvae can cause damage. The female adult flies and stabs the leaves of the plant for feeding and laying eggs. The larvae sneak into the leaves and petioles to cause damage, forming irregular snake-shaped white insect passages, destroying chlorophyll, affecting photosynthesis, and damaging plants. The leaves fall off, causing flower buds and fruits to be burned, and seriously destroying seedlings, mainly damaging more than 110 kinds of plants in 22 families such as cucumbers, tomatoes, eggplants, peppers, cowpeas, broad beans, soybeans, kidney beans, watermelons, wax gourds, and loofahs. In recent years, with the substantial increase in vegetable planting area, vegetables have become the second largest crop in my country, and the effective control of Liriomyza sativus has attracted more attention. Insecticide resistance is growing rapidly.

Bemisia tabaci (Gennadius) belongs to the genus Bemisia tabaci (Gennadius), which has been found in Greek tobacco in 1889 and has been distributed on all lands in the world except Antarctica, with as many as 600 species of host plants. , has become an important pest on vegetables, commercial crops and garden flowers worldwide, and its harm is increasing day by day. Bemisia tabaci is one of the main pests on tobacco. It not only punctures tobacco leaf juice, secretes honeydew, induces soot, and causes direct loss of nutrients in tobacco leaves. More importantly, it spreads a variety of plant viruses, seriously affecting the yield and quality of tobacco leaves. Quality, the harm caused by the virus disease caused by Bemisia tabaci is much more serious than the harm caused by piercing and sucking. Soon after a large outbreak of whitefly, the viral disease it spreads will follow. Geminiviruses transmitted by whiteflies have caused devastating damage to crops in many countries and regions, and there is a trend of increasing year by year. Conventional medicaments for controlling whitefly now mainly include organophosphates (such as chlorpyrifos, acephate, etc.), carbamates (such as methomyl, carbosulfan, etc.), chlorinated nicotinyls (imidacloprid, Acetamiprid, Nitenpyram, etc.) and insect growth regulators (buprofezin, pyriproxyfen), etc. Due to the biological characteristics of the pest itself, the frequent use of chemical pesticides and the blindness of medication, Bemisia tabaci has developed resistant biotypes to various chemical pesticides including neonicotinoids worldwide. Therefore it is necessary to seek novel insecticidal substances that are difficult for pests to develop resistance.

Spirotetramat has high efficiency and broad spectrum, and can effectively control various piercing-sucking mouthpart pests, such as aphids, thrips, psyllids, mealybugs, whiteflies and scale insects. The main crops that can be applied include cotton, soybean, citrus, tropical fruit trees, nuts, grapes, hops, potatoes and vegetables. Studies have shown good selectivity for important beneficial insects such as ladybugs, hoverflies and parasitoid wasps. One of the modern insecticides with two-way systemic conduction properties. The compound can move up and down throughout the plant to reach the foliage and bark, thereby controlling pests such as on the inner leaves of lettuce and cabbage, and on the bark of fruit trees. This unique systemic property protects young stems, leaves and roots from the growth of pest eggs and larvae; long-lasting.

Cyromazine (cyromazine) is an insect growth regulator low-toxicity insecticide with very strong selectivity, mainly active against Diptera insects. Its mechanism of action is to distort the larvae and pupae of Diptera insects in shape, and the adult larvae are incomplete or inhibited. The drug has contact and stomach poisoning effects, and has strong systemic conductivity and a long duration of action. Cyromazine has no toxic and side effects on humans and animals, and is safe to the environment.

However, the above single preparation of spirotetramat and cyromazine encountered a series of problems in actual use. For example, the production cost of spirotetramat preparation is relatively high in field use; cyromazine, as a chemical pesticide, has a good control effect on pests at present, but in order to improve the control effect of pesticides on pests, farmers continue to increase the use of pesticides. In addition, pests are prone to develop resistance to pesticides.

The 3rd instar larvae were used as the material in the experiment. Using the method of soaking leaves, dilute the test agent into 5 concentration gradients, soak the leaves with the surviving Liriomyza larvae in the liquid for 5 seconds, blot the leaves with filter paper, put them into a constant temperature and moisturizing petri dish, and check for death after 48 hours Rate. 10 bean leaves were taken for each treatment, and each treatment was replicated 3 times, and 10 larvae were used for each repetition. The mortality rate and corrected mortality rate were calculated, the regression equation of toxicity and the LC ₅₀ value of lethal intermediate concentration were obtained by the probability value method, and the co-toxicity coefficient was calculated by Sun Yunpei's method.

Co-toxicity coefficient CTC=100×virulence index of actual mixed use/virulence index of theoretical mixed use.

When the co-toxicity coefficient is significantly greater than 100, it indicates that there is a synergistic effect; when it is close to 100, it indicates that there is an additive effect; and when it is significantly less than 100, it indicates that there is an antagonistic effect.

Example 12: Toxicity determination of insecticidal compositions against whitefly nymphs:

Using the leaf dipping method, dilute various chemicals into 5 concentrations in equal gradients, pick several hibiscus leaves containing 1-2 instar Bemisia tabaci nymphs from the insect culture room, and remove eggs and other insect states under the microscope. , each leaf has about 40-50 1-2 instar nymphs of Bemisia tabaci. Soak the leaves in the liquid medicine for 5 seconds, take them out, put them in the room to dry, put a layer of filter paper in the petri dish, put the leaves on the filter paper in the petri dish, wrap the petiole with wet cotton balls to keep moisture, cover and cultivate Dish cover. A total of 30 treatments were used in the experiment, and each treatment had 3 replicates. The leaves were soaked in water as a control. On the 3rd day, the death of 1 to 2 nymphs of Bemisia tabaci was checked under a microscope (those with shriveled body and withered yellow color were considered dead). The mortality rate and corrected mortality rate were calculated, and the regression equation and LC ₅₀ value of toxicity were obtained by the probability value method. The co-toxicity coefficient was calculated by Sun Yunpei's method.

Co-toxicity coefficient CTC=100×virulence index of actual mixed use/virulence index of theoretical mixed use.

When the co-toxicity coefficient is significantly greater than 100, it indicates that there is a synergistic effect; when it is close to 100, it indicates that there is an additive effect; and when it is significantly less than 100, it indicates that there is an antagonistic effect. The test and calculation results are shown in Table 2:
