It's easy to get the material of the invention and easy to operate; besides, it can be widely used in full scale production.

The invention discloses a bactericidal composition compounded by bromothalonil and methoxy acrylic acid esters, which is characterized in that: active components of the bactericidal composition are the bromothalonil (A) and one of strobilurin fungicides (B); the ratio of the weight percentage of the A to the B is 1:80-80:1; and a synergizing agent salicylhydroxamie acid (SHAM) is used in the composition. The active components account for 1 to 90 weight percent of the composition; and the synergizing agent salicylhydroxamie acid (SHAM) accounts for 1 to 50 weight percent of the composition. The composition has novel components, scientific compatibility and obvious synergism, solves the problem that the single bactericide has single action mode and high consumption and is easy to generate resistance, has the characteristics of high efficiency, low toxicity, environmental protection, and no risk of teratogenesis, carcinogenesis or mutagenesis, accords with the development direction of bactericides, can be widely applied to prevention and control of anthracnose, downy mildew and powdery mildew of vegetables and fruit trees, Mycosphaerella black rot, fusarium wilt, anthracnose, powdery mildew and downy mildew of melons, and plagues, and particularly has high effect on the anthracnose of various crops.

The invention discloses Acinetobacter lactucae and an application thereof to degradation of a quorum-sensing signal molecule DSF (diffusible signal factor). The invention provides a bacterial strain of Acinetobacter lactucae QL-1, the bacterial strain is preserved in a China Center for Type Culture Collection on September 11th, 2017, and the preservation number is CCTCC NO: M2017487. The bacterialstrain can employ the quorum-sensing signal molecule DSF as a sole carbon source for growth, and 2mM of DSF signal molecules can be completely degraded in 15 hours with high degradation activity andstable degradation performance. The bacterial strain QL-1 has substantial biocontrol effects for black rot caused by Xanthomonas campestris XC1, and the bacterial strain also has characteristics of fast growth speed, simple cultivation method, good adaptation capability without easy variation, and great application potential for promotion of control of pathogens which are pathogenic depending on DSF; and at the same time, the product can reduce the problem of abuse of pesticides, and provides a new thinking for biological control of plant diseases.

The invention provides a molecular detection primer for sweet potato black rot germs and an application of the molecular detection primer. The specific primer comprises an upstream primer DyB1F: 5'-TTCATCGTCAGGAATACCG-3' and a downstream primer DyB2R: 5'-GACCTTGGCTTTCTTGCTGTA-3';; and a specific amplification product with 509 bp of segment length can be amplified from pure DNA (deoxyribonucleic acid) of the sweet potato black rot germs, a tissue of a germ-carrying disease plant and soil by PCR (Polymerase Chain Reaction) amplification and agarose gel electrophoresis so as to detect the sweet potato black rot germs quickly. The specific molecular detection primer and the application thereof can be used for the quick, sensitive and specific detection of the sweet potato black rot germs in the germ-carrying soil, sick bodies, the disease plants and seedlings in the production practice, can also be used for the early diagnosis of field diseases and the monitoring and identification of the germs, and provides the control of the diseases caused by the sweet potato black rot germs with reliable technical and theoretical bases.

Egg candling methods and apparatus are provided wherein black rot eggs can be identified and removed. A method of identifying live eggs includes illuminating eggs in a carrier with light from a light source; receiving light passing through each egg at a light detector; generating an output signal that corresponds to light received at a light detector for each respective egg; analyzing the output signal for each egg to determine opacity of each egg; removing eggs having an opacity less than a first opacity value; and removing eggs having an opacity greater than a second opacity value that is different from the first opacity value.

The invention discloses a pyraclostrobin-containing sterilization composition. The pyraclostrobin-containing sterilization composition comprises active ingredients including pyraclostrobin and iminoctadine tris(albesilate), the weight ratio of which is 1:10-8:1, preferably, 1:5-5:1. The composition can be prepared into emulsifiable solution, water dispersible granules, wettable powder, suspending agent, emulsion in water, microemulsion and microcapsule suspending agent allowable by agriculture. The pyraclostrobin-containing sterilization composition has a good control effect on main diseases such as sour rot, penicilliosis, penicillium digitatum, black rot, anthracnose, botrytis cinerea, grape gray mold and watermelon stem blight occurring in the storage period of citrus, and compared with the existing single preparation, the prevention effect is obviously improved, and the pyraclostrobin-containing sterilization composition has obvious synergism.

The invention discloses a preparation method of triazolone. Triazolone is a triazole fungicide which is high in efficiency, low in toxicity, low in residue, long in lasting period and strong in internal absorption performance. Triazolone has very strong activity to some pathogenic bacteria in a living body, is very poor in in-vitro effect, has stronger activity to hyphae than the activity to spores, can be conducted in plant bodies after being absorbed by each part of a plant, has the effects of preventing, removing, treating and fumigating rust diseases and powdery mildew, and the like, and also has the effects on various crop diseases such as northern corn leaf spot, barley leaf blotch, wheat leaf blotch, pineapple black rot, maize head smut and the like.

The invention belongs to the field of agricultural agents, and provides an agent composition capable of being used for preventing and curing black rot of tobacco roots and application thereof. The agent composition is prepared from an active ingredient A and an active ingredient B, wherein the active ingredient A is sodium selenite, and the active ingredient B is prochloraz or carbendazim; the weight ratio of the active ingredient A to the active ingredient B can be 1:(1-50). The agent composition has a very good effect of preventing and curing the black rot of the tobacco roots and can effectively retard the agent resistance and reduce the agent applied dosage.
