In order to reduce the usage amount of pesticide fertilizers and protect the natural environment, seed coating agents are receiving increased wide concern. In this study, the active constituent (pesticide) and inactive components (surfactants and film former) of the seed coating agents were screened and optimized by the wet sand processing superfine grinding method. The fungal inhibition test of pesticides showed that thifluzamide, fludioxonil, pyraclostrobin, and difenoconazole have an obvious fungal inhibitory effect on wheat sharp eyespot, take-all, and root rot. LAE-9 and polyacrylamide + carboxymethyl cellulose (CMC) is recommended for the safe surfactant and film former, respectively, based on the seed germination test. Moreover, 6% difenoconazole · fludioxonil flowable concentrate for seed coating (FSC) stimulates the seedling growth of wheat, advances the growth of root, and improves biomass in the field trial, meanwhile, the control efficiency reached above 80%. Thus, we suggested it can be used as an effective seed coating agent for the control of soil-borne diseases in wheat. The seed coating agent has the characteristics of disease prevention, increasing crop yield, and safety of environment, which is of significance in practical application.

Flax is a minor oilseed crop in Canada largely exported to the European Union for use as a source of industrial oil and feed ingredient. While flax could be genetically engineered (GE) to enhance nutritional value, the adoption of transgenic technologies threatens conventional flax market acceptability. Harvest seed loss of GE crops and the persistence of GE crop volunteers in the seed bank are major factors influencing transgene persistence. Ten commercial fields in Alberta, Canada, were sampled after harvesting conventional flax in 2006 and 2007, and flax seed density and viability were determined. Additionally, artificial seed banks were established at two locations in Alberta in 2005 and 2006 to quantify persistence of five conventional flax cultivars with variability in seed coat color (yellow or brown) and α-linolenic acid (ALA, 18:3cisΔ9,13,15) content (3 to 55%) at three soil depths (0, 3, or 10 cm). Harvest methods influenced seed loss and distribution, > 10-fold more seed was distributed beneath windrows than between them. Direct harvested fields had more uniform seed distribution but generally higher seed losses. The maximum yield loss was 44 kg ha−1or 2.3% of the estimated crop yield. Seed loss and the viability of flax seed were significantly influenced by year, presumably because weather conditions prior to harvest influenced the timing and type of harvest operations. In artificial seed bank studies, seed coat color or ALA content did not influence persistence. Flax seed viability rapidly declined in the year following burial with < 1% remaining midsummer in the year following burial but there were significant differences between years. In three of four locations, there was a trend of longer seed persistence at the deepest burial depth (10 cm). The current study predicts that seed-mediated gene flow may be a significant factor in transgene persistence and a source of adventitious presence.

Sari. Trichoderma spp merupakan golongan fungi yang bersifat antipatogen, khususnya layu kecambah, sedangkan bokashi merupakan kompos yang diperkaya dengan beberapa mikroba yang bermanfaat bagi pertumbuhan tanaman.Tulisan ini merupakan rangkuman penelitian pot menggunakan kompos Trichoderma spp sebagai pelapis benih terdeteriorasi disertai bokashi kotoran hewan yang dilakukan pada tanah lahan kering dan tanah sawah pada tahun 2014 dan 2017. Percobaan pertama membandingkan efektivitas beberapa agen hayati sebagai pelapis benih pengaruhnya terhadap vigor benih dan hasil tanaman. Hasil percobaan menunjukkan penggunaan kompos Trichoderma hasilnya lebih baik dibandingkan agen hayati lainnya. Hasil percobaan selanjutnya menunjukkan  bahwa pelapisan benih dengan 1 sampai 3 g  kompos Trichoderma spp per 100 butir benih pengaruhnya tidak nyata dibandingkan dengan penggunaan pelapis benih berupa pestisida, baik terhadap vigor  maupun hasil biji per tanaman. Pemberian bokashi sebaliknya secara nyata mampu meningkatkan hasil biji per tanaman . Pemberian bokashi 15 t ha-1menghasilkan biji seberat 19.83 g per tanaman  atau setara dengan 2,379 t ha-1 atau 27,3 % lebih tinggi dari kontrol.Kata kunci : Benih terdeteriorasi, pelapisan benih, Trichoderma, Bokashi Abstract. Trichoderma spp is a group of antipatogenic fungi, especially seedling wilted, while bokashi is a compost enriched with some microbes that are beneficial to plant growth. This paper is a compilation of pot experiment using Trichoderma compost for coating deteriorated seed and accompanied by bokashi on dry land soil and paddy soil in 2014 and 2017 respectively. The first experiment compares the effectiveness of several biological agents as a seed coating of its effect on seed vigor and yield. The results of first experiment showed that the use of 2 g Trichoderma compost 100 seeds-1 was better than other biological agents. However between 1.2 and 3 g of Trichoderma compost per 100 seeds was not significant effect on seed vigor and yield. The results of experiment showed that the coating of seeds with 1 – 3 g of Trichoderma spp compost 100 compared with pesticide seed coatings. Increased of yield only affected bokashi application. Application of bokashi 15 t ha-1 abble to produce 19.83 g seed per plant or equivalent to 2.379 t ha-1 or 27.3% higher than the control.Key words: deteriorated seeds, seed coating, Trichoderma, bokashi

The article analyses the universalization of the seed material by its physical and mechanical properties by means of pre-sowing treatment, resulting in the formation of an artificial shell. As a result of the generalization, a technological scheme of obtaining an encapsulated seed and a design of a seed coating machine was proposed. A simulation model of the sowing accuracy process from the internal friction coefficient of seeds at different root mean square deviations of seed sizes is proposed. The regression equation for the influence of the dynamic mode of operation of the developed experimental sample of seed coating machine is established. According to the experimental studies’ results, the static and dynamic friction coefficients of the encapsulated vegetable seeds on the steel and plastic working surfaces of seed coating machine were established. Under the production conditions, experimental tests were conducted to compare the seedlings of untreated, coated, branded and encapsulated seeds of vegetables by the quality of prepared seed material and sowing time.
